I think I have the same issue that colomomo123 has. In particular, after installing the FeedBurner plugin, I’m told to point the FeedBurner source feed to: https://www.aventureforth.com/feedburner_165600/
However, this does not seem to be valid (“We could not find a valid feed at that address”).
Also, I don’t have a .htaccess file at all–it looks like one was never created.
Any ideas?
