The RSS feed contains a URL like “supercharge.info/?center=25.970508,-80.141165&zoom=11”, but this just takes you to the supercharge.info homepage. I think it is missing ‘map’ in the URL and should be supercharge.info/map?center=25.970508,-80.141165&zoom=11
[note: I removed https:// from URLs to stop them being rendered by the editor]
I can’t help with the bug, but if you put a single backquote ` before and after a URL it will display it without converting into a link. Make sure to use the quote on the ~ key, not the one on the " key!
