how to obtain rss url?

It would be:

https://www.grapefruitgirl.com/edibles/?feed=rss2

thanks very much! that of course worked. one last question, when i added my feed it says “title unknown” and i’d like to customize that of course. where does one customize that info in the code?

“where does one customize that info in the code?“

Go to Options > General, and put something in Weblog title.

strange, i added a title/info to the “Weblog title” and it still shows at “title unkown.” could it be a cache issue?

Just force a *hard* refresh of the feed page (typically Ctrl+F5, or hold down the Ctrl key while clicking the reload/refresh button in your browser).
