Hi,
With Joomla 3.10.11 (see support info in site details) for some reason, "JEvents configuration" loads an empty page with this error : « 0 Joomla\CMS\Form\Form::getInstance() could not load file ».
The Call stack stops at JROOT/libraries/src/Form/Form.php:2295
Thus we can not load JEvents global settings anymore.
Thanks for helping,
Regards
