@amoun May be a tricky code of matomo set under "advanced" in "settings" of special collection caused, that my provider blocks any trial to save changes. This way i can not delete those added lines. (Only this one collection is affected).
so I think to do a hard correction. But I don't know where the settings of each collection could be found.
I would appreciate you support.
Thanks and regards, will
I don't understand the problem ??.
Each collection has a [Settings] tab which should then show the [Advanced] tab. I have it but can't see how to enable or disable it. It that what you are looking for ??
