When I try and update an old post I get
Whoa, something is not right...
Your nonce didn't verify... can you hurl this log to the developer at firstname.lastname@example.org please?
There's been lots of errors in recent days with this plugin presumabley because of lack of testing before the updated plugin gets released.
I've now removed the plugin and next week I'll set some time aside to write up a plugin to do soething similar. I'll then release it to the WP repository after it's been tested and cinfirmed working.
Keep an eye on my profile page or the newest plugins rss
