For the last week or two I've had a strange problem with the forum index. When I first visit the index and select a sub-forum, the page reloads rather than taking me to that sub-forum. This problem only occurs the first time I visit each day. From then on things work fine.
I have also noted that when I first visit the index, some of the posts listed in the "last post" column will have that day's date. But after I select a sub-forum and the page reloads, those dates will be changed to yeaterday's date. It is all very strange.
