Thread:Project:Support desk/Private wiki database error/reply (3)

I have checked how Yahoo Small Business web servers are set up and it seems like you only have limited access to MySQL. Usually in their menu, it is called "database mangement" or something like that. A tool, which is very often offered to do things with the database is phpmyadmin; maybe they offer that. A quick look at their site shows these features are not available on the basic plan. If you're on the Advanced or Premier plans, you should have them.

As to why this problem occured: I don't know. Maybe the objectcache somehow got corrupted. If your backup was old enough (I guess a few days should mostly do), MediaWiki should throw away the old stuff it now found in the objectcache table, which effectively fixes the issue as well. Although this problem should not happen, it is nothing to be terribly worried about; after all that is only cache data.
