Hi all,

Really strange error here. I have a few rich text editors inside of the grid layout control. All works correctly until I try to insert a link at which point I get this error on save:

Authorization error: Unauthorized access to URL: /umbraco/backoffice/UmbracoApi/Content/PostSave

We are running version 7.3.1 in a load balanced environment. Absolutely any recommendations on what I can try? I'm running out of ideas.

Edit

Digging into the Umbraco source code it looks like it might be hitting this in the ContentController but I can't see why adding a link would do this?

//lasty, if it is not valid, add the modelstate to the outgoing object and throw a 403
        if (!ModelState.IsValid)
        {
            display.Errors = ModelState.ToErrorDictionary();
            throw new HttpResponseException(Request.CreateValidationErrorResponse(display));
        }

Thanks
