For as long as I can remember, my rich text editor hasn't worked.

rich text error

At this point I'm not sure whether it's a security issue or a web config issue, but the problem does affect all sites under the same project if that's any help. I am logged in as admin and this is local development. I just tested it in production, and the error does not occur there.

Therefore, my gut tells me that it's some type of a file issue. But any direction is appreciated.

Here's what the log spits out:

5916 12:40:17 ERROR Application error. Exception: System.Web.HttpUnhandledException Message: Exception of type 'System.Web.HttpUnhandledException' was thrown.

In my web.config, I have the default text editor defined as:

<setting name="HtmlEditor.DefaultProfile" value="/sitecore/system/Settings/Html Editor Profiles/Rich Text Default"/>

Which should be the default value.

When I look in the core db content editor, the tree does appear to expand as referenced and the files look as though they are all there (specifically the /sitecore/system/Settings/Html Editor Profiles/Rich Text Default folder).


  • The last error that starts with ERROR Exception in alarm clock event subscriber is not related to your problem. Remove the contents of the SubmitQueue folder under Data and that error will go away. Dec 15 '16 at 19:37
  • Much appreciated. Your suggestion did work for getting rid of that error. I will update the question to remove that part as it's extraneous to the issue at hand. Dec 15 '16 at 19:42
  • @DmytroShevchenko post that as an answer ;) Dec 15 '16 at 21:07
  • @ZacharyKniebel nah, that was a separate error and a separate fix. Dec 16 '16 at 5:45
  • I have the same error and I've recently upgraded to 8.2. Could you fix it or still an issue?

I have compared your rich text editor request with my local setup. It seems the Sitecore path is missing in the request that you have mentioned. Your request:

http:/site.com/sitecore/shell/Controls/Rich %20Text%20Editor/EditorPage.aspx?da=core&id=%7B04733BD9-54B4-45F2-8661-EF964BCAA 7E6%7D&ed=FIELD98016355&vs&la=en&fld=%7B217FDF39-763D-4E3D-8193-B8929DF02D00%7D& so&di=0&hdl=H98016451&mo&pe=0&fbd=

My rich text editor's request captured through Fiddler (notice the path):

  • So the question then is, where could I make that change to make the path correct? Dec 19 '16 at 19:30
  • Before this, did you try adding the sitecorepath in it manully & tried accessing it ? was it working ? please confirm. Dec 21 '16 at 7:29
