Basic SVG iconset generator

I understand - it was simply a generic error message box saying the xml file failed to generate.
Interestingly, I reinstalled the script and restarted DOpus. I just tried to generate the message for a screen shot and the script worked again, mysteriously.

Thanks for your time to reply.

have you tried this one, (just checked and is still working)

Glad to hear it works fine again.
If it was to fail again, do not hesitate to take a screenshot of the error, and also have a look at (and copy/paste) the script logs.
