I have a problem when I see a slider.
The message is as follows:
An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.”
I tried to search google for a solution but without success
Sorry to hear of the problem you are having.
Please Go to > cpanel > Security > Modsecurity and then disable mode security.
Some hosts hide the mod-security setting from their customers as a security measure so please contact your host in this case.
