Sigil 2.6.2 - html open fails, do not understand error message

[Derell Licht]

I am trying to open an html file, and convert it to epub.
When I open the document, I get an error message (shown below)

However, I cannot find either the Clean Source preference, nor the Mend XHTML Source Code option, anywhere in the program.
Can someone please give me some pointers on this??

right click in CodeView and select Mend. Or as it says go to Sigil Preferences and turn on clean/mend source on open. Then try reopening an html file.

Where exactly is your screen capture from? That dies not look like any error message or font that Sigil normally uses?

Are you sure you are using Sigil 2.6.2 and not some earlier version?

The error message says there is am xml parsing error in the specified file in line 30 where it expected a closing tag '>' character but got a ':'.

Open that file and copy and paste lines 29 - 31 here and people can help. But turning on Mend when opening poorly formed html (not xhtml) files is almost a requirement as html is not xhtml.

Okay, responses:
1. Yes, definitely Sigil 2.6.2; I can upload a copy of the About dialog if ye wish, but it is 2.6.2
2. The font is different from default because I use a Windows Theming program called WindowBlinds to set custom fonts, but it doesn't do anything to the messages from any programs.
3. The closest that I can find to "Mend XHTML Source Code on Open" is:

Edit -> Prefs -> General Settings -> Basics tab -> 
Mend Not Well Formed HTML Source code On:

and both Open and Save are already checked...
But I *still* get this error on opening the file.
4. here are lines 29 through 32:

*
 * @licend  The above is the entire license notice
 * for the JavaScript code in this page.
 */

As can be seen, there is no colon there...
