I have never experienced so many problems with a forum before?
I have never experienced so many problems with a hosting company before.
I have the new forum up and ready on a different host but have struggled for months to get a database export that I can upload (so that you and all your posts appear on the new forum)
In general, a white screen is caused by a 500 (server) error which means some script somwhere is stuck in a loop. The best thing to do is to relaod the forum from your original point of entry (a bookmark?). You will probably find that your post and been posted or your PM sent.
