“Your attempt to edit this post has failed” WordPress Bug

I’ve been searching all over the internet and haven’t been able to find a solution for this problem – Your attempt to edit this post has failed – has anyone seemed to find a usable answer?

I’ve looked at adding the plugin “Your Attempt Fix” but that is no longer available, and I have even updated two of my plugins to no avail.

There has to be some sort of answer either from the WordPress gurus or just a quick work around. This issue is becoming a huge pain in the you know what.

Any helpful suggestions would be appreciated.
