Hi,
I just upgraded my website to Joomla 4. It took me some time, but it worked. But when I try to open pages in SP Page Builder, I get an error with the text: Cannot read properties of undefined (reading 'data')
I have uninstalled SP Page Builder and re-installed it. But no change. I have PHP 8.0.
What can I do?
Best regards, Judith Schoorlemmer
Hi there,
I appreciate you reaching out. I sincerely apologize for this oversight. Trying to find out the solution. But, No solution found. Can you give me time to check your site on my localhost?
-Thanks
Hi Toufiq,
Thank you for your reply, of course I'll give you time to check it. Glad that someone is helping out, because I've tried for many, many hours now.
Best regards, Judith
ive had this on 3 different sites over the last 2 months ...all have had the last 3 updates and it hasnt helped..the issue comes and goes. Judith, who do you host with ? im on siteground.
I have a small, personal host, which I have good contact with. But I don't think this is the problem. page Builder worked just fine with Joomla 3, on the same server.
I have the eactly the same issue as described above.
Jooma 4.4.1
Page Builder 5.2.2
Please update me with any progress made.
Hi there,
I've successfully downloaded your site backup using the Akeeba Backup extension and installed it on my local server. Everything appears to be functioning correctly. However, your console displayed an error indicating difficulty loading resources. If you're using CloudFlare, consider disabling the rocket_loader. Additionally, you may want to attempt the process again after disabling mod_security on your hosting server. This should help resolve the resource loading issue. If you encounter any further challenges or need additional assistance, please feel free to reach out.
-Thanks
Hi Toufiq,
I assume your reply with directed to Judith and her system.
I found some additional information which may help.
I have one particular user who is accessing the page builder through the administrator backend. When he logs in the Notification checks all show as errors. EG 'Error on checking overides.' Unknow Joomla', 'Unknow Extentions', Unknow request' .
When accessing the page builder he gets the 'Cannot read properties of undefined (reading 'data') message. If he clicks the 'Back to admin' button, this loggs him out, when he re-logs in the notifications all show green and the page builder works fine.
Sometimes the user would click on the back button of the browser, in this case the issue continues until the 'Back to admin' button is clicked on the error message.
This happens every day for this one user, any thoughts on what may be the cause?
Thanks
Paul
Can i get the site login credential?
I can't seem to find my answer to you. Maybe others should better start a new topic? As lots of people sharing this topic for maybe different problems?
My host is not switching the mod_security off and I don't use cloudflare. But I have an errorlog of the server, which may explain more? I'll put it in the hudden section.
Did you change the administrator login URL?
No I didn't?
Hi Toufiq,
I have the same problems as Pauls friend have on my system in a different way.
I made a backup with akeeba an moved to another server. Set it up with kickstart and mysql 8.
Then using component sppagebuilder entering settings, etc. always "Cannot read properties of undefined (reading 'data')"
What can I do?
Thanks
Udo
Will you please provide me the Joomla administrator access to check the issue?
So... anything new yet? I'm still struggling with the error and can't reach my pages.
Please provide me with the correct login URL for administrator access of administrator. Cause the administrator login URL redirects me to the home page. Thanks
Hi Toufiq,
This is strange, as I didn't change anything at the site. But I edited your logon info and sent it to the hidden section.
Hope this will work out.
Judith
Administrator url redirect me on home page instead of login page. Thanks
Hi, I have the same situation like you. The only way to edit pages is to click on the back button. It bings me back to a login page, after redo the login it works as normal.
But it is very annoing.
Maybe you have added any code or used any third party extensions on your site. That's why occurred this problem. Thanks
No, the same site (backup) work on another hosting.
Will you please provide me the Joomla administrator access to check the issue? Besides, Please share a screencast of the full scenario. Thanks
here you can see what append in my case: https://files.fm/f/hvct4xckmk
Where exactly did you click? I can't see your mouse pointer. Thanks
Here you can find a new video with the mouse: https://files.fm/f/vsvuwp3yvn
This are the steps:
Did you change administrator URL?
I did not provide login credentials.
With my hosting provider I have changed the version of MariaDb (now with one supported by Joomla 5). With some browser works better, but not with Chrome.
Please check the screenshot.
Hello, I also had a problem with invisible pages!
The list of all pages created in SP Page Builder has disappeared in the admin panel.
When I try to somehow access the list of my pages, sometimes the error message Cannot read properties of undefined (reading 'data') pops up.
Previously, all my pages were divided into categories, after updating the SP Page Builder component, I noticed that all the created categories disappeared, but the site worked and did not require updating, so it’s difficult for me to say at what point the problem with invisible pages in the admin appeared SPPB panel.
I came to the conclusion that the problem was in the categories created by earlier versions of SPPB, so I decided to try to do this...
Now in the SPPB admin panel I select to show only what is in the SERVICES category and select the language I need. This is the only way I can get each of my pages back.
There is another way, export each page through (Fronted editor) and then import it again through the SPPB admin, but here’s how to delete the old page...???
Will you please provide me the Joomla administrator access to check the issue?
Hello! I sent you your login information. I have created a backup copy of the site but please be careful! This is a big website project. Thank you!
Super administrator access, please. Thanks
Sorry, you are now a super user!
I've successfully downloaded your site backup using Akeeba Backup, and it's running smoothly on my localhost. It appears that your server might be blocking the loading of resources for the Page Builder, which is likely the cause of the issue. Thank you.
but before the SPB update everything worked as it should, we did not change the server. how do we fix this?
I have checked older version of Page Builder. But, the result is same. Will you please disable the mod_security and check again. Thanks
Sorry, I don’t quite understand where I can disable this mod_security?
Can you tell me the version name that was previously? Which is work smoothly.
-Thanks
It's hard for me to say which version it was. the site was created on version SPB 3.x.x, then we switched to Joomla 4 and imported all pages into SPB 4.x.x. We noticed that the list of categories was missing, but all the pages were visible. Previously, all our pages were arranged by category because there were a lot of them. Then we switched to version SPB 5.x.x. but all pages were edited only in the Frontend Editor, and recently we noticed that the list of all pages was missing in the SPB admin panel. I can try to upload a copy of the site to a test subdomain, check how the site will work if it is loaded again.
Please create a staging site with your backup and lets try to check your older version. Thanks
Hello. I am experiencing the same problem on admin panel. Cannot read properties of undefined (reading 'data')
Please try to check todays released version and let ue know the update. Thanks
Thanks, but it is the same. You can check yourself with credentials I sent in previous comment.
Thank you, Toufiq! This update (SPB v5.2.8) fixes everything. All my pages are visible again.

@Admir Meskovic Please check now and let me know. Thanks
Hi, I have been in the process of creating a clone of my live website in order to test out the upgrade from J4 to J5 and I now have this same problem. This is what I have done so far:
I am still on J4 as not happy to perform upgrade until I have a fully functional test site. Any advise is welcome..
Can you provide me a Akeeba backup?
Before creating a backup, please change the configuration JPA to ZIP file.
Hi, cannot figure out how to send you a PM, but here is link to ZIP backup file:
It works fine on my end.
mmmm. I've just tried using a different browser (in case cache issue) but same result. Do you have any suggestions as to why its not working on my test server?
Maybe your server blocked to load the resources of Page Builder.
Disable the mod_security or rocket_loader from from the cloudflare.
I'm also still having the same issue. I can't edit any page from the backend and when I try from the frontend, I get to the editor, but the page appears blank - I can't see any of the content.
My site is running:
I can't disable Mod_Security as I'm on a shared hosting platform. But this was never an issue with Joomla 3 or 4 and previous versions of SPPB, on the same hosting.
I'm using Cloudflare for SSL, but all other optimisation settings are disabled.
Please advise.

Hi, we're also encountering this on the latest build 5.4.2 (and a couple previous ones) on Joomla 4.4.9.
I can grant super admin access to our test site if helpful. Also, LMK if OK to stay in this thread, or better to open a new one. Thank you for any help!
Can you provide me site backup using Akeeba backup extension. I have tried but, it failed. Thanks
Toufiq, our backups are massive as it's a super big site with a built-in CRM engine (CiviCRM) and a ton of pix so giving you a back-up is not really an option. Not to mention we can't just pass the data outside of our systems for privacy reasons. Any other ways I can try to troubleshoot? Were you able to access the test site, using the credentials I provided in my previous post in the hidden section? Thank you so much.
Disable the mod_security or rocket_loader from from the cloudflare.
Thanks, that did the trick, but... that's not appropriate for production sites as mod_security is there for a reason. Couple questions, then, please:
When we have checked your issue in our hosting & it works fine(mod_security is enabled). I think your hosting server blocked to load the resources of extension. Thanks
