Can't save components

[pmallet]

I am running into this same problem with GS 3.3.13. I can edit themes just fine, but when I try to save components it redirects me to /admin/components.php with a file not found error. From what I can see from previous threads, it sounds like a problem with mod security, but I don't know what to do about it. My site is hosted on a shared Apache host (greengeeks.com), so I do not have direct access to my Apache settings. Is there something I can do to my .htaccess file to fix this? If not, what should I ask my host support folks to do for me? Thanks!
