Hello Philip,
Warning: SMF_header_include(/Forum/SSI.php) [function.SMF-header-include]: failed to open stream: No such file or directory in /websites/LinuxPackage02/di/dc/ot/didcottownfc.com/public_html/mambots/system/SMF_header_include.php on line 67
Fatal error: SMF_header_include() [function.require]: Failed opening required '/Forum/SSI.php' (include_path='.:/usr/local/php5/share/pear') in /websites/LinuxPackage02/di/dc/ot/didcottownfc.com/public_html/mambots/system/SMF_header_include.php on line 67
Seeing this error, I think this is not the error which is produced by JoomlaHacks bridge. It's Ortio's bridge. As I know, JoomlaHacks bridge doesn't use mambots.
If you previously had Ortio's bridge installed, you can try to uninstall it again. But if I am not wrong, Ortio's bridge does not uninstall all parts (The mambots still remains). So, if you want to use JoomlaHacks bridge, you must manually uninstall the mambots too.
Hope this can help you solve the problem.
Best Regards,
Arifin FinLy
