First of all thanks for the plugin, is very helpful!
I updated today to newest version (1.1.30) on wordpress 3.41 and the site breaks (shows a 500 internal error), when I deactivate de plugin the site works... and it used to work with the previous version.
This is in my local environment using mamp with php 5.4.4. I still haven't pushed to the live site.
The php error log shows:
[28-Aug-2012 16:07:58 UTC] PHP Fatal error: Cannot re-assign auto-global variable _POST in /Applications/MAMP/htdocs/notebook/wp-content/plugins/profile-builder/front-end/wppb.register.php on line 182
Can you provide a fix please?
