Have you cleared or disabled your browser cache? If not, give that a whirl.

Note that whenever you upgrade umbraco, you'd have to make this customization again. We don't officially support changing the theme. Also make sure to change the version in ClientDependency.config so that client cache gets cleared (as well as clearing your browser cache).

First of all thanks for taking the time to respond.

I cleared my cache and it still displays the default theme.

I looked into the ClientDependency.config file in the Config folder but I can't find anything that pertains to Codemirror or the theme it uses.

This is what my ClientDependency.config looks like.

<?xml version="1.0" encoding="utf-8"?>

<!-- For full details of the client dependency framework, visit https://github.com/Shandem/ClientDependency It manages CSS and JS file dependencies per control without having to worry about duplicates. It also manages the combination, compression and minification of all JS & CSS files. NOTES: * Compression/Combination/Minification is not enabled unless debug="false" is specified on the 'compiliation' element in the web.config * A new version will invalidate both client and server cache and create new persisted files -->
<clientDependency version="209273982" fileDependencyExtensions=".js,.css" loggerType="Umbraco.Web.UI.CdfLogger, umbraco">

  <!-- The composite file section configures the compression/combination/minification of files.

Persisting files means that the system is going to save the output of the compressed/combined/minified files to disk so that on any subsequent request (when output cache expires) that these files don't have to be recreated again and will be based on the persisted file on disk. This saves on processing time. -->

Is there somewhere else I should looking, is that the right directoy for ClientDependency.config?

Thanks again.

Change clientDependency version="209273982"to something else.. like clientDependency version="213512"

Sebastian that doesn't seem to work either, no worries I guess I will have to stick with the default theme.

Thanks again for your help.

is working on a reply...
