Hi Seblod,
Working on Joomla 3.10.11 - Seblod 3.23.1 with PHP 7.4 and try with PHP 8.0, 8.1 and 8.2
I have a form with a Group-X field where I have a upload_image field.
When I'm working with PHP 7.4 every thing work like a charm and I have my image uploaded and reachable.
When I try PHP 8.0 -> 8.2, I get an erro message :
"Attempt to assign property "value" on null"
If I go back to PHP 7.4, it works again. So it occur only when changing my PHP.
Any advice ?
