# 404 error when saving theme settings

 * In WP Admin, under “Appearance” and then “Theme Settings”, when I choose to save
   theme settings, I get a 404 error. I very recently saved changes to my theme 
   settings with no problem; this just started occurring. I can’t think of any changes
   I’ve made that might cause this and am at a roadblock troubleshooting it myself.
 * More details: From here:
 * wp-admin/themes.php?page=[theme name]
 * Clicking to save takes me out of WP Admin and to the site, where there is a 404
   error. Strangely, the URL remains the same:
 * wp-admin/themes.php?page=[theme name]
 * When I refresh the page, it stays where it is, on my site with the 404 error.
   But if I copy and paste that URL into a new window, or even the same window in
   my browser, it returns me to the theme settings page in WP Admin, which remain
   as they were, attempted changes unsaved.
 * I’m using multiple installations of WordPress. This is suddenly occurring in 
   every single instance (3 of them), even though I haven’t done anything to 2 of
   them for some time, well before I noticed this problem occurring (as I mentioned,
   just a week or so ago I saved theme settings with no problems). My main site 
   is in the root folder. I have additional sites in subdomain folders. This problem
   now occurs with all of them, including my main site.
 * I’ve tried creating a brand new subdomain. I then did a fresh install of the 
   WordPress 2.9.2. Starting from scratch. I then installed a theme I know has theme
   setting options. It saves fine in the fresh installation. It’s only my previous
   installations that are broken somehow.
 * Any assistance would be appreciated!

 * Probably something has been changed from server end. Sometimes this happens due
   to mod_security and PHP Suhosin. Make sure that they have not enabled any of 
   this recently.

 * My host did indeed say it had something to do with mod_security. I don’t know
   what that is or what they did, but they said they resolved it, and indeed it’s
   working now. Thanks!
