@AramZS I've double-checked and had cleared caches previously (which if not done wouldn't have forwarded as I'd had the forward value set to 0 before.)

I've cleared everything out and reinstalled the new .org version from the repository and am finding the same issue seems to persist. (Even testing in a new browser install.)

One thing I am noticing is that a lot of my older posts were actually imported into my self-hosted install from either other non-WordPress sources or an older WordPress.com account. When editing these which don't have any values set for `pf_forward_to_origin`, I notice that the UI default for PF is for them to `Forward` rather than the typical default of `Don't Forward` which I get for new posts.

I'm also noticing that these older posts have the original site's GUID set in wp_posts which means that they're being forwarded to those URLs (some of which don't exist anymore). I'll try to circle around and make a caveat note in the documentation of this for others who may experience it (and not know why).

Perhaps there's some other glitch in my database causing this? Since @regan008 has tested it and confirmed on your side (and the code looks correct to me), I'll throw in the towel. Since I've got to make some of these additional GUID changes (along with some others) in my database anyway, I'll just go in and add values for all these older posts so they're "forced" to work anyway.

Thanks, as always, for such continued work on a fantastic tool!
