Sorry for the delay. I didn’t get a notification of your reply.
Metabox before clicking “Share Now” (although it has been clicked several times before): https://share.getcloudapp.com/L1uXzLD9.
I tried to take a screenshot of the metabox with the error message showing but it disappears when I click anything (including the button to take the screenshot) and when I type anything (like the hot key to take the screenshot).
I did see that you want the diagnostic info posted here, but I’m uncomfortable posting all the details about the website in a public forum. If you’d like the diagnostic emailed to you just let me know.
Thanks in advance and I’m sorry again that I missed your post.
