Post Notification conflicts with auto save

Hi there,

I think there might be a problem with Post Notification. I’m currently running 8 blogs, 4 on a testing site, 4 on a live site.

Only on the live site, and only on computers other than mine (doesn’t seem to be browser specific), I get the following error message after posting:

“Your attempt to edit this page/post has failed. Please try again.”

After reading https://conradmiguel.com/wordpress-25x-your-attempt-to-edit-this-pagepost-has-failed-please-try-again, I deactivated the ‘post notification’ plugin, and the problem disappeared. Also, after reading the post, I tried to uncomment the suggested line and leave ‘post notification’ enabled, and again, it fixed the problem.

Anyone else have this problem? Anyone know what could be causing the problem?
