 * Hello and thank you for developing this plugin.
 * This error msg started today on the site I am using SnapID. Attempting to login
   via SnapID or the regular login fields failed. Upon deactivating the SnapID plugin,
   I was able to login via regular login.
 * Upon updating SnapID and deactivating all other plugins, the same error msg continued.
 * PHP Warning: session_start(): Cannot send session cache limiter – headers already
   sent (output started at /home/wp-user/public_html/wp-content/plugins/snapid-two-
   factor-authentication/includes/snapid_wp.php:46) in /home/wp-user/public_html/
   wp-content/plugins/snapid-two-factor-authentication/includes/snapid_wp.php on
   line 46

 * No apologies ever necessary with me. This didn’t get posted as the first part
   of the error msg, my bad.

 * Hi Curtis,
 * Thanks again for your patience. While we are unable to reproduce the problem 
   we do have an update to the plugin ready for distribution. We think it might 
   fix the issue. Would you like to give it a shot before we distribute it publicly?
 * If this update doesn’t fix the issue, we will dig deeper to see how we can reproduce
   the issue.
 * Thx!
