I’ve pasted two URLs below, the first should go to a specific section and the second to the main troubleshooting page. I think that works OK? I don’t see anything to do with quoting.
How are you copying the URL that you are unable to paste?
I completely believe that the feature can get in the way in some circumstances but I’m having trouble understanding exactly what the problem is and how to reproduce it. Once I understand it better, there might be an option I can configure to avoid the issue, or a bug in the Discourse software that we could track or report.
