Hi, same problem as described here: https://www.gavick.com/forums/security-and-configuration/can-t-edit-save-any-gavick-module-nor-template-23794.html
Discovered problem today. The only thing I did yesterday was to deactivate the GK Extended Cache plugin so FaLang worked properly on the menus. However I have tried to reactivate GK Extended Cache, purge all expired cache and deactivate FaLang as well, but no luck.
There is also this message at the bottom of the pages with these problems: Fatal error: Allowed memory size of 201326592 bytes exhausted (tried to allocate 8589934591 bytes) in /hsphere/local/home/jungl137/beta.jungle-sports.com/administrator/components/com_menus/helpers/menus.php on line 184, but have 192 MB memory which should be more than enough.
K2 and JCE Editor works fine, so the problem is restricted to the admin area.
Any idea what can cause this?
