Upgraded to PHP 5.2.14 - Some languages are broken

[moman]

I've recently had my server upgraded to PHP 5.2.14. Currently, memcached is still down, so some functionality isn't working in my other add-ons, but it looks like vBET is.

However, only a few languages are currently working!

Danish works: PentaxForums.com - Pentax Photography Forum
Polish doesn't: http://www.pentaxforums.com/forums/pl/

This notice is shown on all forum pages:
Notice: Use of undefined constant DIR - assumed 'DIR' in ************************************************************************************************************************../forums/includes/vbenterprisetranslator_functions_vbseo.php on line 18

If I change this code in the vbet functions_vbseo file:
if (!defined(DIR)) {
define('DIR', (($getcwd = getcwd()) ? $getcwd : '.'));
}
to just
define('DIR', (($getcwd = getcwd()) ? $getcwd : '.'));

the warning disappears, but my problem isn't fixed. Any idea why this would be? FYI, there are no notices or errors currently being shown on the vBET pages.

I copied and am still using my old php.ini file, so the same settings are being used as before.

Thanks for your help!
