Hi, after I installed Contact bank plugin, the error message showed up:
Warning: exec() has been disabled for security reasons in /home/u654001559/public_html/wp-content/plugins/contact-bank/contact-bank.php on line 29 Warning: exec() has been disabled for security reasons in /home/u654001559/public_html/wp-content/plugins/contact-bank/contact-bank.php on line 30
How can I fix it?
