After doing a clean install of PP8 on a testboard, this is what I get: A community photo gallery - My Photo Gallery - Google Chrome_2012-02-17_13-09-38.jpg
vB4 integration is fully activated (3 times yes in PPAdminCP), and the path settings for integration, esp. URL settings to forum, have been double checked.
What I found is that the vB
calls to css.php go nowhere, that seems to be the case on Reeftalk too (which I referenced).
This is on a pretty much vanilla vB4.1.10 test installation, with forum URL set correctly and "Always use Forum URL as Base Path" set to yes, if this is of any help.
