I am very aware that my site need full security. Have you ever experienced that whenever you logged in to your WordPress admin dashboard you’re always getting a message like this;
Not Acceptable!
An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.
I opened a support ticket in HostGator on August 23, 2016 at 02:46 AM and Hostgator replied to my support ticket on August 24, 2016 at 11:01 AM.
Since I am using HostGator as my webhost, I prefer to ask the customer support about this matter and this is their answer.
