UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 5 Support General Settings won't update

I just moved to a new host & after I re-uploaded all my files, I went to update General Settings but when I clicked "Submit General Settings Now" it just gave me a blank white screen. How do I fix this??? I checked all the permissions & they looked right too.

I have version 5.45c

Please reply ASAP!
