Cannot publish blog posts after update
I recently updated a client to 2.5.4 and the latest blog app. They're having a problem publishing posts from a draft state after modifying the post.
So say they've got a post with some text in it, and then they change one of the sentences and add a couple of photos, then adjust the toggle from draft to published and hit the save button, the page hangs and 'gets stuck' and the green save banner doesn't appear.
Then their changes aren't saved on reload.
Any idea what might be going on?
