Don't have the same issue on local host, just in the hosted environment at softsyshosting. I'm using the silver plan listed here http://www.softsyshosting.com/Win08Hosting.aspx
. Full trust is enabled and all functionality in the site works fine on the hosting environment, except for rss feed deletion. The rss feed was created locally and then I moved the database over, which might be something to note.
I've been able to workaround this issue, but just curious why deleting an rss feed causes this problem on a shared environment. This could be caused by the hosting enviornment, my setup, or just a combination of things, but otherwise everything else works fine.
