I've installed WordPress Automatic Upgrade and now i'm unable to upgrade my WordPress version.
When i press Automatic Upgrade in my WP control panel i face with the eror message below.
Warning: exec() has been disabled for security reasons in /var/www/vhosts/cansurmeli.com/subdomains/blog/httpdocs/wp-content/plugins/wordpress-automatic-upgrade/wpau_prelimcheck.class.php on line 81
I gave the CHMOD of the file as 777 in case the problem was occuring because of that but nothing changed.
So what is the problem?
