Blank pages

On more than one occasion I have come across blank pages when I try to load certain pages. One of which was the "time for another silly picture thread" in General and the "Michael Jackson's dead" thread in Metropolis. When I click on the thread title to load the thread, I get a white, blank screen. Other threads load correctly, but these two don't. It says done loading at the bottom of the page. I have tried it out on two different computers and two different browsers (Firefox and IE) and gotten the same result.

cheers mate. yes i have had a major issue getting the site back online and one of the weird things is these odd blank pages. i will try to clean the dbase again and keep my eye on the log files. if you see any other strange behaviour please tell me ;)
