Thanks guys. Just an update...I found the culprit. Not VB at all....but a too full server. /usr was so full it couldn't handle even writing correct error logs (thus the error=0 in the error message)
My server holds 16 gig and yet we had it at capacity with the vb of ours. Its not the first time a full server did funky things to the processes of the vb...and each time I forget about this kind of behavior. (Each time its a bit different in its symptoms)
We recently upgraded and had additional backups of the database...somewhere between 1-2 gig in size.
So...we deleted two backups and *poof* we are in business again and my hacks are all functional again and the other postings.php and private2.php are now working fine.
Thanks sooo much for ya'lls help. (And thanks to Logician who found my server tooooo full as the answer)
Any idea if adding a hard drive to my server would help with storage space on a rapidly growing database? :-) (I even prune inactive members monthly.)
