 * Hi [@teertha](https://wordpress.org/support/users/teertha/)
 * This indicates that you’re running an outdated version of PHP on your host. The
   minimum required version of php for WPUM is 5.5, you’d need to request to your
   host to update to at least 5.5.

 * Hey [@wpusermanager](https://wordpress.org/support/users/wpusermanager/), I was
   having that same issue so I updated my PHP to 5.6 and it caused my site to pull
   a HTTP error. In debug mode, it showed the weird shortcodes error mentioned in
   other support threads. Not sure what to do here — really need to get this plugin
   back up and running ASAP. Please advise.
