Unexpected Application Error Message Misleads

[aamplugin]

The "Unexpected Application Error" message many times misleads users because it does not represent the true state of execution.

WordPress core returns false value when you are trying to save the same option twice. For example, go to the Posts & Terms tab and try to save the same Teaser Message twice. The first time it'll save just fine. However, trying to save exactly the same message the second time, you'll see the "Unexpected Application Error".

AAM should be smart enough to successfully acknowledge that duplicated information was saved.
