I'm copy and paste some text with hyperlinks to a custom post field and the post content doesn't save. However if you switch to the plain text tab, the post saves just fine. But since my data have hyperlinks that option is useless at the moment.
Link to a page where the issue can be seen: hidden link
I expected to see:
Saved post data
Instead, I got:
Nothing
Note: My workaround, was to enable the default editor on the post type and it fixes the issue, however, I need to remove that box sooner than later since it cause confusion in the backend.
