This is probably a difficult question because i can't give you a lot of information. When i open the edit screen in the adminside of a module it's being shown for a split second and the the page refreases to a blank page with a input type select.

I already tried to uninstal the admin template and reinstal but the issue is still here. It happens with any admin template i tried so far accept the oldschool Hathor admin template.

I have no idea where to look for the problem. I hope someone else encountered this issue before and has a solution. Or atleast an idea where to look.

Tell me if there is any information i can give you to clearify. Ps I run the latest Joomla version 3.6.5

Kind regards, Jeroenenter image description here

I Fixed it by reinstalling Joomla core files.

First make a back-up. Then components -> Joomla -> install

ps. this is available form Joomla 3.6.x


This issue does not require to re-install Joomla. All it takes to fix this issue is make sure to clear Joomla's cache and browser cache and refresh the page.

It's a caching issue usually after updates, as some js have been changed for the backend, but the backend still loads old cached js.
