Hi, i have updated a few days ago one of my websites http://www.ego-alterego.com to 3.1 version of wordpress. Since then (with or without a direct connection with the update) posts from the past (november 2010 for example) re-appear on the homepage with their posting dates changed into present date. I have read that there is a plugin available that does this but i don't have anything like this installed.
On this website i have posted graphic related posts and a few youtube videos. I noticed that it seems that videos/music/lyrics tagged posts seem to be moved as new, but maybe this is only a coincidence.
What should i do, does anybody else have this problem?
