Thread:Project:Support desk/Database error after updating to 1.20.4/reply (5)

Well, the change you found seems to be, if im not mistaken, for the upcoming mediawiki 1.21, so perhaps it could be possible that these columns are still needed for 1.20?

Nevertheless, i will check my extensions for any outdated versions and report back, as a temporary fix i created these two columns to get my wiki up again...
