I'm trying to use Newbbex 1.8, but when I try to access a forum, all I get is:
Fatal error: Cannot redeclare newbbex_createmeta_keywords() (previously declared in /var/www/test/modules/newbbex/include/functions.php:2) in /var/www/test/modules/newbbex/include/functions.php on line 39

That error doesn't make much sense (or does it?) because line 2 is where the function is declared and line 39 is where the closing bracket (and only that) is.

Any ideas as to what may be causing this?

Probably the file is included somehow twice (as this error happens on the first function definition).
Try by changing the include of this file to an include_once.

That did the trick! Thanks a lot ghia. Really appreciate having you here
