Using wp_check_post_lock() would allow me to gain a lot of flexibily, I really like to sound of it – unfortunately I may be failing at understanding how to properly use it: I get a “Uncaught Error: Call to undefined function wp_check_post_lock()” both on the front/backend. Could you point me in the right direction perhaps (I understand this is more of a WordPress request at this point, but if you have a few minutes to spare I would appreciate it a lot!).
Meanwhile I’m gonna open up a ticket as you suggested.
Thanks in advance!
