uncaught exception: [CKEDITOR.resourceManager.load] error

Hi!
I had the same issue, and I fixed it by modifying the next line in ckeditor.js :
CKEDITOR.stylesSet.addExternal(f,b[1]?b.slice(1).join(":"):CKEDITOR.getUrl("styles.js"),"");

with this one:

CKEDITOR.stylesSet.addExternal(f,b[1]?b.slice(1).join(":"):CKEDITOR.getUrl("plugins/styles/styles/default.js"),"");
