- Can’t edit an existing user, no reaction
- Can’t create a new user, no reaction
- Can’t change a user to be admin, no reaction
- Can’t update my profile (e.g. change language), no reaction
With no reaction I mean that clicking any of the save or edit buttons will do nothing. The page stays the same.
I am running v2.16.0
I deleted the browser Cache.
I used different browsers (Firefox, Chrome and even Internet Explorer)
I deleted piwik/tmp/*
I have no idea how to activate PHP errors
I have no idea where to check web server error logs
I reupload all Piwik files from the latest version
Any ideas how to overcome this?
