I don't know what the deal is, but it won't allow me to enable this. Every-time I press on the option labeled, "Comments/Ratings" under Advanced Settings, it says that this file doesn't exist. I would like to enable this option, but I don't know how to get around this.... problem. Here, this is what it says to me whenever I try to go to that option:

Fatal error: Uncaught exception 'Exception' with message 'File does not exist - ./services/comment_options.xml' in /usr/home/main/domains/gotop100.com/public_html/system/xml.functions.php:7 Stack trace: #0 /usr/home/main/domains/gotop100.com/public_html/system/exec_service.functions.php(61): parse_xml('./services/comm...') #1 /usr/home/main/domains/gotop100.com/public_html/manager/exec_service.php(48): ShowFields('comment_options', Array) #2 /usr/home/main/domains/gotop100.com/public_html/manager/advanced.php(195): include('/usr/home/main/...') #3 {main} thrown in /usr/home/main/domains/gotop100.com/public_html/system/xml.functions.php on line 7
