I uploaded version 1.1 to our website a while back, and today when i logged on to check on things i get these weird errors(i hadn't made any changes myself, they seemed to come out of nowhere and i'm stuck as to why there there)

I have the same problem after upgrading to 1.2. The problem goes away if I delete all the entries from the posts folder (this is not desirable of course).
