i've one wordpress installation on /lp folder, when i finished the website i moved it to the root, everything works fine except one plugin "Global Gallery" that gave me an error (you can see here http://www.cagliaridinamoacademy.com/gallery/)
At the line 935 of file.php there is this code:
define('FS_CHMOD_FILE', ( fileperms( ABSPATH . 'index.php' ) & 0777 | 0644 ) );
How can I fix it? Thank you
