It has happened on a few occasions that I would login and see that another admin was editing a post, or he would login and see that I was editing the post. In fact, either instance, neither of us had been anywhere near that post for days. In once instance, I had even turned off my computer and it still showed that I was editing the post.
These are minor annoyances.
However, tonight my partner logged in to find that a subscriber was currently editing the page!
Since the subscriber is a friend of his and he knew he wasn't editing, it didn't pose a big problem, but it raises the question: how? Why?
It seems like it's not possible for a subscriber to edit a post, so it must be WordPress acting up. Is it a glitch or is there something wrong on my end that I need to fix?
