Hello,
I hope you’re doing well. I’m sorry for the experience you’ve had so far.
To look into this issue more closely, could you please share temporary Super Admin access (inside the hidden content box)? I’ll check this and update you as soon as possible.
Please make sure to keep a full site backup before sharing the credentials, just to be safe.
Best regards,
OK
How can I do to share images with the posts?
Hi Alejandro Lengua,
Sorry for the delayed response. I am checking the issue now.
Meanwhile you can share your images by uploading them in your online server or drive, then share the link with us here.
Moreover, what it the issue in this page, please? https://escuela.indecopi.gob.pe/index.php/cid/publicaciones.html
Best regards,
That specific page also has the ID=53, to which an item has been added that is currently hidden, because when it is made visible, it cannot be previewed.

Thanks for the details. Are you using any caching system? The changes are not reflecting immediately.
However, could you please check now?
Best regards,
Yes, we use Sucuri CDN

Did you make any change?
BTW let me know your IP so I can add it to Sucuri's whitelist
Yes, I have made changes to the file:
templates/shaper_educon/sppagebuilder/addons/feature/site.php
The error should no longer appear on the affected pages.
Please let me know if it is resolved on your end as well.
Note: My IP is not static; it is dynamic.
The final user told me that when you made the change, some document download buttons were removed. Could you check it again?
Please check the arrow in the attached picture

Hi,
Sorry to hear about the trouble you are facing.
May I take a full site backup, please? I need t check it on my local, as there are some caching plugin doesn't let the changes reflect on time.
Best regards,
Yes, sure you can
BTW the download buttons I mentioned in my previous post is still missing
I have also updated this image for more clarity

Hello,
I have made some changes. But cannot see reflection. Would you please clear you server side cache and check again?
Kindly, do let me know if your issue is now solved or not.
Best regards,
Thank you! It seems to be working well now.
I finally wanted to ask you if it would be safe to upgrade the plugin,
because the last time I tried to do it automatically from the Joomla panel, it gave me an error.
Hi,
Yes, you can update. Please make sure you have latest backup before upgrade to be on the safer side.
Best regards,
Thanks for the update, I have just managed to upgrade both Joomla to version 5.4.1 and SP Page builder to version: 6.1.2 however I noticed this text in the settings page https://www.dropbox.com/scl/fi/11evbsdis4qsm8eure9u2/Captura-de-pantalla-2025-12-11-021941.png?rlkey=a8spxxr265lpebv6h6s6fv5ij&dl=0
BTW I also wanted to know if the Shaper_educon template I am currently using also needs to be updated
