Thread:Project:Support desk/Error: 1146 Table 'pjk uawiki.user' doesn't exist (localhost)/reply

Your database currently misses at least the tables "user" and "user_newtalk". From browsing a few pages in your wiki I got the error messages that also the tables "valid_tag" and "watchlist" are missing - and almost certainly other tables as well. The table structure of these tables must be restored to give MediaWiki at least a chance to work properly again. However, you will also need the table contents: E.g. the user table contains information on your wiki's user accounts - the wiki cannot work without it. Without the stuff from the watchlist table your wiki might still work, but the information on which user watched which pages would then be lost.

To get your wiki working again, you will at least have to restore the user table - and those other tables, which are missing as well. See DB for an overview of the tables which you should have. If you want to get the wiki working again, it is absolutely essential that you get this information back.

From what you describe, I consider the current state to be broken beyond repair. I would not try to somehow fix the broken state, which you have now (e.g. by manually recreating the structure of missing tables or so). Instead, I would go back to the newest backup. That will be far easier.
