I really dont see anything wrong with the link you posted
Its possible you could have corrupted information I suppose but I would not know why a server move would do that. I have stated several times a couple things to do like disabling other mods you have doing maintenance but never really got any replies to those posts.
Disable that seo
plugin what happens? What other hacks have you recently installed you need to look at all pertinent changes besides the server move. I mean your server move could be the first time you noticed the issue. It could have been there on the old server.
