Make sure the EPiServer VPP settings are correct - check path for all providers of type VirtualPathNonUnifiedProvider in episerver.config.

Hello Eric, I had a similar problem and asked about it here:

http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=54567&epslanguage=en

I never got to the source of the problem so will be interested to hear if you resolve it at your end.

Licens problems on that server? tried with an IIS reset? Open the network tab in the browser and check if you get any missing files (404)?

Hi!

Could you check if the page is rendering in Quirks mode? This is required to layout the different areas for the page.

Hi Eric,

Try this out:

1.Copy /MyEPiServerSite/App_Themes to C:\Program Files (x86)\EPiServer\CMS\6.1.379.0\Application

(App_Themes is already present here, paste and overwrite the file structure)

2. Stop or restart IIS

3. Go back to /MyEPiServerSite/ and rename (or delete) App_Themes

4. Reload the site. Done, UI should be back to normal.

Are you running EPiServer Commerce?

If so, make sure that your C:\Program Files (x86)\EPiServer\CMS\6.1.379.0\Application\App_Themes\Default\Images\Tools\dark contains the file commerce_manager.gif

We saw the same problem on a different site.

Check with Firebug and the Net tab to see which requests return 404. That will narrow your search down...

Had this answer from EPiSupport, did fix the problem

1. Copy /MyEPiServerSite/App_Themes to

C:\Program Files (x86)\EPiServer\CMS\6.1.379.0\Application

(App_Themes is already present here, paste and overwrite the file structure)

2. Stop or restart IIS
