Thanks, I appreciate the fix and the reply!

I had assumed the proxy was dynamic (i.e. the Hexbear server checks for embedded resources hosted on external domains and replaces them with the proxied links on-the-fly when serving requested content), but based on the earlier images/videos in this thread not being proxied even after the config has been updated it looks like it happens when records are committed to the database? That's unfortunate, and I presume that's why you're considering possible further action. In an ideal world the database entries in the intervening period would be amended, but that does seem like a hassle, and I won't pretend to know how involved that might be.
