OK,

I checked back on changes made.

The PM Notify stopped working after installing the PM Ban addon and UBB Code fix.

(Pre PM 3.0)

No changes were made to forumdisplay.cgi since, so the problem lies most likely in the code changes made in the Ban addon.

Help please!

Workin on it... this is the final component I need for UBBIM, so I'll add it to CYMPM 3.5 I think... cheers!
