My instance of a WordPress Multisite is completely screwed up. I was having very slow loading times on pages and admin sites. Thought if I upgraded to WordPress 3.2.1 things might (fingers crossed) resolve themselves and it has only seemed to make things worse.
I think the problem may have been a plugin that grabbed other posts from another WordPress blog (that is on the same domain but not same WordPress instance) and inserted those posts into a site on the current multisite instance that is screwed up. From what I have read this has caused big problems for other multisite users.
Unfortunately I can't seem to recover from the original problem of slow loading pages. I cheked on mysql and the WordPress tables don't seem to be corrupt. I deactivated all plugins and still seem to have this issue. So i tried upgrading to 3.2.1 and now I can't even really get to some Admin pages for sites, other still slow loading.
What would be my best course of action? I do have a copy of the DB pre update as well as a copy of all WordPress files. The thing I thought to do was to revert back to 3.19 and export each site, start with a fresh install of 3.2.1 and then import each site.
Anyone have any better ideas which are less time consuming? Better ideas in general?
Im running Apache 2.2.20, PHP 5.2.17 and Mysql 5.X on a Windows Server. Hosted by me. The rest of the site is not slow at all and I have other WordPress sites workign
