Can't access SPPB after upgrade to J6; libraries/loader.php

Asked by Karen Dunne 3 months ago Last activity 3 months ago

I've upgraded a site from Joomla 5 to Joomla 6.

SPPB pages will not display in the backend. Instead, it only shows the following error and a button to go back to admin:

Warning: Cannot redeclare class joomla\cms\filesystem\folder (previously declared in /home/demo/public_html/rta/libraries/vendor/joomla/filesystem/src/Folder.php:19) in /home/demo/public_html/rta/libraries/loader.php on line 576

Warning: Cannot redeclare class joomla\cms\filesystem\file (previously declared in /home/demo/public_html/rta/libraries/vendor/joomla/filesystem/src/File.php:19) in /home/demo/public_html/rta/libraries/loader.php on line 576

This is Joomla! 6.1.1, php 8.4.22, SPPB 6.6.1, Helix 2.2.6

Hi there,

Thank you for reaching out, and I apologize for any inconvenience caused by this oversight. To better address the issue, could you kindly provide Joomla administrator access? This will enable me to thoroughly investigate the matter and provide you with a prompt resolution.

I appreciate your cooperation and will ensure to get back to you as soon as possible.

Best regards,

Toufiqur Rahman (Team Lead, Support)

Thank you, Toufiq.

I'm not able to provide admin access at the moment. The site is on a dev server.

Do those warnings look familiar to you? Screenshot:

Please let me know whether the Behaviour - Backward Compatibility 6 plugin is enabled or disabled. If it is disabled, please enable it and check again.

Is it possible to create an staging site to check the issue?

Hello, I have the same issue, hoped that with Pagebuilder 6.6.2 the problem could be resolved.

Thank you for your help.

Hi Toufiq,

I have the site in a staging area that you can access. But, I'm hesitant to add the login credentials here because I can see Gina's hidden content. I don't think that's supposed to be visible to me. So that makes me think that hidden content won't actually be hidden and I don't want to share login credentials publically.

I created a chat with Claude.ai and the results may help with troubleshooting. I've shared that chat here:

Please advise.

Here's a screenrecording of the issue: https://www.loom.com/share/7f78f782cd994a5fb24acf57a48a71d5

P.S. When installing SP Page Builder 6.6.1 and 6.6.2, the installation completes but generates the following warning:

"Unexpected token '<,"
... is not valid JSON"

Thanks, Karen. For now, disabling the reporting errors helps. I don't receive the JSON warning. It looks like everything is working normally.

Toufiq, and Gina.

The hidden content is visible to me. I should not be able to see the login credentials. Nor would you want anyone other than Joomshaper staff to have your login information.

Initial solution

components/com_sppagebuilder/helpers/autoload.php

Find out this code

if (!class_exists($original)) {
    class_alias($alias, $original);
}

Replace with this code

if (!class_exists($original, false)) {
    class_exists($alias);
}

Note: Final fix will add next release.

-Thanks

I just realised that the front end error still appears:

Warning: Cannot redeclare class joomla\cms\filesystem\file (previously declared in /home/httpd/vhosts/conrad-scuol.ch/httpdocs/libraries/vendor/joomla/filesystem/src/File.php:19) in /home/httpd/vhosts/conrad-scuol.ch/httpdocs/libraries/loader.php on line 576

can you give me an e-mail address for Login? I changed them.
