@goncatin In global configuration please enable "Debug System" to Yes and set "Error Reporting" to maximum,

Additional you can check error_log or similar file at your joomla root directory.

If I dissable the SEF URL the form works, but doesn't show the modules linked to the original menu item, so I think is the same issue that Your text to link here...

I've just tested it (using JUForm Lite) - and the issue is fixed by reverting #19099 or applying my patch #19498

Before patch (3.8.4):

• Menu item (form) placed at: http://localhost/j384/index.php/test-form
• Submitting redirects you to: http://localhost/j384/index.php/component/juform/ which throws an error

After patch:

• Menu item (form) placed at: http://localhost/j384/index.php/test-form
• Submitting redirects you to: http://localhost/j384/index.php/test-form

I confirm that, OctavianC, applying your patch works fine.
