Response code: 401

Yes, delete the tumblr_post_id custom field from your post. This will be visible in the Custom Fields meta box of any cross-posted entry. If you do not see the “Custom Fields” meta box, make sure you have enabled it in your Screen Options.

When you delete that value, Tumblr Crosspostr thinks it has never cross-posted that post before and will create a new one, giving it a new Tumblr ID. When you erased the old post, Tumblr Crosspostr kept trying to edit a post on Tumblr, which no longer exists, and so 401 Not Authorized is the expected and correct response in such a situation.

This is one reason why it’s wise not to use the Tumblr editing interface if you don’t need to. And, with Tumblr Crosspostr, the point is: you don’t need to, so, y’know, don’t. ??

tnx for the quick reply and solution.

And yes, I’m gonna use only WordPress to edit posts. But I just started to use TC and was playing with the possibilities.

Gr, Remco.

Hello, thanks for the quick fix! Worked like a charm.

I did this as well, but I deleted the tumblr_post_id field and not the value. I added a custom field called tumblr_post_id and then removed the value, and now I get a 401 no matter what I do. Any suggestions? Thanks.

In case anyone made the same mistake that I did above, I fixed it by disconnecting and then reconnecting the plugin WP.

Settings > Tumblr Crosspostr > Disconnect…Then reconnect

Works great now.
