[kshs92]

Hello,

Need your help urgently.

I installed MGC Chatbox Evo 3.2.1. But I got a fatal error.

Warning: include([path]/mgc_cb_evo/plugins/init_startup.php) [function.include]: failed to open stream: No such file or directory in [path]/includes/init.php(331) : eval()'d code on line 116

Warning: include() [function.include]: Failed opening '[path]/mgc_cb_evo/plugins/init_startup.php' for inclusion (include_path='.:/usr/local/lib/php') in [path]/includes/init.php(331) : eval()'d code on line 116
