When attempting to post an article to Joomla (version 4.4.13), I encountered the following error:

Error loading data from the server.
Call to a member function getWebAssetManager() on null

Would you be so kind as to let me know what might be causing this issue? Thank you very much for your assistance.

Can I ask how this is related to 4AI?

You should enable Joomla Debug system option in Joomla global configuration, this should give you a full list of files involved in the issue.

Hi Yannick,

I hope you’re doing well. I’ve discovered that the error I encountered in 4AI when attempting to “Publish article to Joomla category” was caused by an issue in my template. I’ve since corrected the template, and the feature is now working perfectly.

Thank you for your patience and support.

Best regards,
Ring
