I installed related-post pluggin, the data base script worked according to message. Now all past posts links don't work. I went to the database and found the posts intact but the links seem to have been broken.
I tried to deactivate the pluggin only the problem still exists. can anyone tell me how to remove the changes to the db, I didn't do a backup to the data base before activating the pluggin and it has damaged the data base linking somehow.
one more point, I am using virtual multi blog pluggin this might be the big kicker.
