Hi,
I have the same problem from yesterday.
I wasn’t able to edit some draft posts and pages. When I edit them, I lost all my work, because the post it’s the same before I the edition.
Even I tried to delete that post, but when I send it to the Junk Folder, It doesn’t work.
I would like to understand what it’s the problem.
Thanks,
