I tried to do a manual update (as described in the docu) and copied the new version to the server. Please note, I have no root access, I can just upload files by ftp.
Now, something went wrong, I am not sure what. It seems, the DB upgrade didn’t work correctly, I get the following error in most widgets now.
SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘idaction_category2’ in ‘on clause’
Any ideas what I could do?
