Having a serious problem here that involves everyone on my blog EXCEPT me. I have 2 authors and 1 administrator who cannot add simple html codes to their articles. Anything from a youtube embed to a new paragraph. All of it disappears if they try to preview their post, schedule, publish, submit for review.
This is really upsetting because I haven't changed any settings, added any plugins or even changed any users. Trying to find a solution has been tedious and time consuming for me and yet I still have no answers.
No additional plugins.
I'll answer any additional questions anyone has. Thanks.
