Hello,
I have the same problem and i have purchased the version 6.
The problem occurs when the client loads this URL :
- http://<MYDOMAIN>/CuteSoft_Client/CuteEditor/Load.ashx?type=style&file=SyntaxHighlighter.css
This URL is loaded in HTTP while all others are loaded in HTTPS in HTTPS contxt.
Even if i click OK on dialog box, the problem is not solved because my environment serves only the HTTPS requests. Result i have a beautifull 502
I think the problem comes from the file : Template.aspx. In this file I retrieve the pattern : <Load.ashx?type=style&file=SyntaxHighlighter.css>
I think we have some mistake in the operations on referrer.
