I have got my hosting provider to look into this for me and it seems like a problem with the open social mod can we please have a fix for this.
Bellow is the problem
Good Morning I traced this back for you, mod security is fine the error relates to how the code is referencing that folder:
Apache-Error: [file "/usr/src/redhat/BUILD/httpd-2.2.3/modules/generators/mod_autoindex.c"] [line 2274] [level 3] Directory index forbidden by Options directive: /var/www/vhosts/MY DOMAIN.co.uk/httpdocs/network/modules/boonex/open_social/shindig/php/gadgets/ifr/, referer:http://www.mydomain.com/nay27uk
Apache-Handler: httpd/unix-directory
Stopwatch: 1313708121606958 34239 (- - -)
Server: Apache
Directory index forbidden by Options directive is the root cause, this is how the folder is referenced by apache, i.e its calling the folder explicitly and not a file directly within that folder.
If you alter the code to call a file within the folder and not the folder on its own, this will then work fine.
