Errors After Upgrading from Joomla 3.10 to 4.4.1: Undefined Method isSite() and Unknown Column m.publish_up

[microvax]

Hello Joomla Community,

I recently upgraded my site from Joomla 3.10 to 4.4.1 and now it is returning the following error messages that seem related to JSN Framework Plugin :

Code: Select all

Copy
Call to undefined method JoomlaICMS\Application\SiteApplication::isSite()  
- File: plugins/system/jsnframework/jsnframework.defines.php (line 60)  
It seems the isSite() method is no longer available in Joomla 4. Was it replaced by another method, such as isClient('site')? How can I modify the plugin’s code to resolve this?

Database Error:

Copy
Unknown column 'm.publish_up' in 'WHERE'  
- File: libraries/src/Menu/SiteMenu.php (line 166)  

However it seems like JSN Framework does not have a Joomla 4-compatible version so I was wondering if you can suggest me any solution.

The error message indicates that JSN is not compatible with Joomla 4 or 5. I recommend restoring a backup and then removing JSN.

Additionally, check all extensions again to ensure they are compatible with the latest Joomla version.

Good luck!

Best regards,

Ron

When you restore from backup delete the files from the server and drop the database tables.

Alternatively you could edit the database to disable JSN?

didn't the pre-update check flag this possible issue before the migration? It would have advised either disable or remove JSN before updating.
