I have tested LMS myself - and must admit I find it both flawed and limiting. So I deleted it again.

If I may suggest using PageBuilders Dynamic Content instead - it gives you many more options, and the learning curve is not that steep.

Thank you for your quick response to my problem.

I don't understand why I can't even edit users? Upgrading Joomla from version 3.x to 5.x went smoothly. There were some issues with isAdmin(), though. I'm providing a link to an archived copy of the site and database. Since the site was created in 2019, it has a certain size.

Thank you, and I hope everything works out for you.

Thank you for the additional details and for sharing the archived copy of the site and database.

Regarding the issue you mentioned about not being able to edit users after upgrading from Joomla 3.x to 5.x: the upgrade process itself may complete without errors, but changes in access control checks and deprecated functions such as isAdmin() can still affect backend operations, including user management. We will need to examine how those permissions and checks were migrated, and whether any extensions or overrides are enforcing outdated logic.

Before proceeding further, I need clarification on one point: the archive you provided is approximately 12.5 GB in total size. This is unusually large for a Joomla deployment, even for long-running sites, so I would like to understand what is contributing to that volume. Large backups can indicate unused media files, logs, cached assets, backup folders inside the root, or other stored artifacts that may not be strictly part of the application. Could you confirm whether the archive includes additional data beyond the webroot and database?

Once I understand that, I will be able to advise more accurately on how best to proceed with analysis and remediation.

Thank you, and looking forward to your update.

Hello Nikolayts,

Sorry for the inconvenience you're experiencing with SP LMS after the Joomla update.

To address this, please replace the file located at:

JRoot/components/com_splms/models/course.php

with the updated file provided in the hidden content area. After replacing the file, the issue should be resolved. If this doesn't solve the issue, please reach out and I'll look into it more deeply.

Best regards

Hi, Atik!

Your file helped solve the problem. Thank you. Sorry for not responding sooner, I was busy with work.

I also solved the user access issue. I had to disable the regacymaling plugin that was generating the error.

Thanks!
