Error when log in

[editor123]

Hi!

I was uploading yesterday 3 products from this forum. After that, even when the plugins were working well, when i want to log in as a user into my forum, appears this error...

Warning: require_once([path]/madp/detection.php) [function.require-once]: failed to open stream: No such file or directory in [path]/includes/functions_login.php(185) : eval()'d code on line 103

Fatal error: require_once() [function.require]: Failed opening required '/home/forosdeh/public_html/madp/detection.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/forosdeh/public_html/includes/functions_login.php(185) : eval()'d code on line 103

It calls to a path that doesnt exist at all

forum is:
http://96.30.0.180/~forosdeh/

I dont know what else can I do.

May i clear the tables where the plugins are installed? I've already delete the plug in files...

thanks!!!
