 * My WordPress website goes blank when I try to activate the plugin with WP version
   4.0. When I delete the plugin, it goes back to normal. I’ve never used the plugin
   on any version of WP before.
 * I’m using a local server with MAMP. I’ve also already increased the member to
   128M.

 * Hi,
 * Are you able to check your MAMP error logs or set WP_DEBUG to true in your wp-
   config.php file? If so, please post the PHP error being generated so we can help
   fix the issue for you.

 * Hi,
 * I saw a new update for the plugin and updated first before doing this. I set 
   WP_DEBUG to true and got this:

 * Thanks for the information.
 * If you update to the latest version of Gravity Forms does that resolve the issue?
