Icons not loading in admin In some instances of my websites the icons don't load properly.  Everything else in the website works, but the icons don't load.  The other websites on the same server with the same php.ini file don't have this issue, just this one website.
I've had that happen before and it was just a matter of refreshing the page a few times to clear it up. If that doesn't work try clearing the control panel resources cache (or just deleting the cpresources folder from your webroot).
