I've had postie running successfully on older versions of WordPress with no issues along with the associated cron job. When upgrading to the latest version though (WordPress and postie), I can't seem to get postie to work. I can activate the plugin successfully and view the postie option settings, but that's where it all ends. When I try to run test config under the options to check my settings, I continually get a 500 server error in the source code. Check it here: http://www.readyaboutllc.com/wp-content/plugins/postie/config_handler.php
View the source of this blank page and you'll see what I mean e.g. <!-- SHTML Wrapper - 500 Server Error -->. Could this be a permissions related issue on the postie directory? I'm really stumped so any help is greatly appreciated.
