What would cause the forum pages to be blank? It shows I have three ctaegories, but they can't be seen..

I have three siites with Geeklog 1.3.10 (most current) and the most current Forum. All three have the same hosting company with the same set up. Only one has blank pages...

Is the code of the page also empty? Or is there at least some header info so it just appears to be emtpy?

try putting in some

echo "xxx";

into the forum code to find out where to output stops maybe?
