I want to remove all the default styles from the FCKEditor drop down styles menu. I have edited the fckstyles.xml file to remove most of them and I also commented out the 'Red Title' line in fckconfig.js but the Red Title style still appears at the top of the styles drop down menu. How can I remove it?

You may need to clear your browser's cache and/or restart DotNetNuke.

There are actually 3 "copies" of fckconfig.js.

(in \Providers\HtmlEditorProviders\Fck\Custom, \Providers\HtmlEditorProviders\Fck\FCKeditor and \Providers\HtmlEditorProviders\Fck\FCKeditor\editor\_source\internals)

Try removing Red Title from all 3, then clear your browser cache and come back in. I also clear the DNN Host cache just for good measure.
