When the Template.aspx page requests the file /CuteSoft_Client/CuteEditor/Load.ashx?type=style&file=SyntaxHighlighter.css

it returns the wrong URL.

<link type="text/css" rel="stylesheet" href='<%=cuteeditor.editorutility.processwebpath(context,page,"load.ashx?type=style&file=syntaxhighlighter.css")%> /'  >

Returns a URL with a port number of 4444, which is wrong.

So it looks like:

https://mydomain.com:4444/...SyntaxHighlighter.css

when it needs to look like:

https://mydomain.com/...SyntaxHighlighter.css  

Removing that line from the Template.aspx is not an option because I use the Syntax highlighting.
