I don't know what I've done but in trying to create an account I get a blank page although it worked previously.

On running the debug tool, I found this error message

PHP Warning: file(includes/spiders.txt) [<a href='function.file'>function.file</a>]: failed to open stream: No such file or directory in /home/mysite/public_html/includes/init_includes/init_sessions.php on line 58

This is the line it is referring to
$spiders = file(DIR_WS_INCLUDES . 'spiders.txt');

Can someone please help?

Thanks
