My UBB has been writing zero byte files, one of which was my 00000001 user record which made it difficult for me to log into CP.
Lately it has been writing 0 byte user records randomly and I just found membertotal.cgi last_approved.cgi and last_number.cgi files were all 0 byte files.

I figured it was lack of disk space but my webhoast says I have plenty. I checked the permissions and all are ok. What chmod should the member files themselves be? 666
or does it matter?

Any idea what's going on?
