Hi team!
I just failed to send a PM and I thought you might want to know. I failed for 2 reasons:
(1) There was apparently invalid HTML in my response - but ALL I did was type in the editor.
(...
This just happened for me again when submitting a reply to a post.
I put in a link that i didn't actually want to be a link, so I used the editor's "Unlink" feature.
I was then unable to submit the post because of invalid html (presumably because of the "<p data-unlink="true">" that was added.)
Someone needs to make sure the WYSIWYG doesn't add stuff that isn't actually allowed.
