1.) Did you by chance rename your admincp directory in Admin Control Panel?

2.) If your not scared of editing your files, you can go to the error-ed line and dump the current working directory. If the files are where they are suppose to be, then your current working directory has been altered for some reason.

Of course this only works if your testing the mod on a test board, which you should be doing.

$cwd = getcwd();  vardump($cwd); die();  //Will display the current working directory
