Installed (twice) for testing....
We use vBulletin 4.1.3 pl8...
Works great, except we have a conflict with Paul's "Display Unread Posts" mod v4.1.7.
https://vborg.vbsupport.ru/showthread.php?t=231060
When the HTTP mod is installed, Paul's mod shows the unread post count (top right corner of web site) as it should, however, when one clicks on the post number to view them, vBulletin shows page saying there are no unread posts, even though there are. You can click the "What's New" tab and the new posts show fine there.
Tried to diagnose as follows:
1. Turned HTTP mod OFF (still a conflict)
2. Disabled HTTP mod (still a conflict)
3. Uninstalled HTTP mod and Paul's "Display Unread Posts" mod v4.1.7 began to work fine again.
4. Re-insalled HTTP mod and problem returned.
5. Finally uninstalled HTTP mod and left things alone.
Hope this helps someone else ..

Doug
