Access denied with code 403 (phase 4)

Hello, I Installed a moodle platform in my subdomain with no problem at all, when i was configuring the appearence, it show me the error 403, and since that i cant accces. Using plesk i saw this error in the log of the subdomain:

ModSecurity: Access denied with code 403 (phase 4). Match of "rx (?:\\\\b(?:gif|(?:cws|f(?:lv|ws)|i(?:d3|hdr|nterplay)|m(?:ovi|thd)|r(?:ar\\\\!|iff)|varg|(?:ex|jf)if)\\\\b)|B(?:%pdf|\\\\.ra)\\\\b)" against "RESPONSE_BODY" required.

I suppose it is an error on permissions, i´ve already give -R 0770 to my moodledata directory and i proved with -R 777 to all my subdomain directory but with the same result, error 403. I appreciate a lot your help!!
