It gets even more interesting.
I installed a clean test copy of vbGallery uploaded to the gallery etc. Checked in my profile to show last post information. Everything works fine. My forum last post shows fine. Nothing in vbGallery affects this so I will keep digging and trying to replicate your issue.
Did you recently do any
vb impex imports etc? any information here to assist that might explain the issue. I need to try and figure what action might cause the problem your describing.
In vb4 the statistics last post info is under the about me tab correct? I checked your site and this is what I am comparing to my install.
