Whenever I click "publish page" in composer to post a new blog entry it says "draft saved successfully." Instead of actually posting and publishing the new page.

On the rare occasion that it does go through and attempt to publish the blog entry, I get a blank white page with the error " {"error":false,"time":"2:02 AM","timestamp":"11\/24\/2013 2:02 am"} " or something similar depending on what time it is.

Help!!!

edit: btw, this is happening in two separate installs of cc5.6.2.1...
edit2: this was a noted bug in 5.6.0.2:http://www.concrete5.org/developers/bugs/5-6-0-2/composer-saving/...
