Error after downgrading to a prior version
After updating my site to 18.104.22.168 I experienced some errors and therefore wanted to roll back my update.
After this I now can't enter my site and I presented with this error:
Class \Concrete\Core\Permission\Key\AddConversationMessageConversationKey does not exist
Does any of you know how to solve this error, so I can regain access to my site.
Any hints are most welcome
Before trying to restore though, try copying the new 22.214.171.124 files across again (or extract them again, whatever you did the first time).
I managed to get acces by copying the file AddConcersationMessageConversationKey.php from another installation.
And Voila ! it worked !
