Ok, got past the last install problem, thanks to Wallphone.
Went through the rest of the install, pointed it to existing forum database etc.... clicked on finish. All looked good. Now I try to start the forum and get this error:
PHP Fatal error: Cannot redeclare class database in /var/www/html/tdocs/forum/library/Framework/Framework.Class.Database.php on line 25
Seems to be relating to this bit of code:
class Database { // Public var $DatabaseType; // The type of database to connect to and use (currently only handles mysql)
I am sure it shouldnt be this difficult, but Im not sure if there is some incompatability with the versions of MySQL, Vanilla and PHP that I am using....
