Since today, one of our sites has a very strange behaviour:
- We cannot save most of our modules, it does not matter if we click save or save and close, it simply returns to the modules list, with all filters resetted
- The module remains blocked (not checked in)
- We can however save some modules (strangely, it does not matter the module position or type, even the standard custom module does not work)
- This happens to existing and new modules
- We tried to disable the Editor (JCE)
- Updated Joomla to 3.8.6
- Used another browser (FF + Chrome) + cleared the cache (Joomla-Cache too)
- Yesterday it worked, we only changed css since then
- Tried to compare the db-record of two modules (one thats working and one thats not), they are identical
- No JS-Errors in the console
- Joomla Debug-Console shows nothing suspicious
Is there any way to debug the saving-process?
Thanks in advance!
Update:
I finally managed to reproduce the issue in clear steps:
- If i assign the module to a few menu items only, i can save it without problems
- If i however set it to "All Pages", i can save it exactly one time, the second time i save the module, it does not work, there is a endless long array in the post data containing the single assignments (?!) to all menu items, but it does not contain the task variable wich says module.apply
So... is there any limit of number of menu items that i can assign modules to? (It is a huge site with countless menu items in 8 languages)
