 * I just loaded up the old 1.2.4 version and it’s working again, but seems to have
   a major problem with 1.3.1?

 * [@stevebradley1](https://wordpress.org/support/users/stevebradley1/), we haven’t
   had any other reports of that, so there must be a plugin or theme conflict going
   on with your site/server configuration.
 * One thing you need to make sure you do when you update is clear any caching /
   CDN services you may have in WordPress or on the server directly. It could be
   that you had cached files, so the new stuff wasn’t working properly, and then
   when you revert back those files match up again so it works.
 * The 500 error basically means a PHP failure happened somewhere, so checking your
   PHP error log should provide more details on that and then we could offer more
   guidance on what could have potentially gone wrong.

 * It’s broken at my end too. Didn’t debug it, but sticking to the 1.2.4 for now.
 * Cheers!

 * [@agentx](https://wordpress.org/support/users/agentx/), when you get time the
   first thing I would look into is your PHP error log and potential caching conflicts.
