Lord Dexter,
Thanks for the reply and yes, it's tempting to assume it's not UBBnews - maybe another hack BUT please be assured - it is.
After each (of 2) separate restores last Sunday, I gave the board a good shake-down and all was well.
But each time when I went to edit a UBBnews session (through cp) I got an error saying that the session "didn't exist". It did - but the restore had somehow caused the board to not register it.
Since there was no way to delete the session(s) through cp, I uploaded the sessions again (vars_ubbnews_1.cgi, +2+3) - cleared cache and then they registered with cp to allow me to delete them and start again with new ones.
On each occasion AFTER I'd created a new session, the re-direct stopped working (I was looking specifically for it)
I went through this whole routine twice.
It seems clear that whatever caused the error, corrupted some part of a file, and that's my challenge.
Which part of which file executes the re-direct/auto return after a post or reply?
That's where I need to be looking.
Any advice??
