When editing a page, and selecting Edit on a content block, the editor icons are not loading (ContentBlock_Edit.png). When right clicking and going to an image to edit it, the icons are no loading there either (ImageEdit.png).
This is the same in IE, Chrome, and FireFox.
I have tried lowering the FrontendResourcesCacheDuration ( http://www.sitefinity.com/developer-network/forums/bugs-issues-/editor-buttons-missing-in-ie ) and flushing the local browser cache and restarting the site in IIS.
I'm not sure what else to try. I don't see any image sprite gif/jpg/png in the directory, and when I look in Fiddler, or any of the IE/FF/Chrome browser tools (FireFoxes built in or FireBug), everything comes back as a 200 or a 304. I'm not seeing any 404 resources.
Are there any hints as to what I should look at next, or how to trouble shoot this?
This is version 7.3 if it makes a difference. Thanks!
