 * Hi guys,
 * When using miniOrange 2 Factor Authentication and the plugin WP-Members I get
   this error in my error_log:
 * `PHP Warning: hash_equals(): Expected known_string to be a string, null given
   in /home/and009k3/public_html/wp-includes/pluggable.php on line 2377`
 * The error is logged in the error_log exactly at the time when I sign in my wordpress
   dashboard.
 * Deactivating any of these two plugins will no longer log the error. But if both
   plugins are active the error is logged.
 * My setup is:
    PHP 7.4 miniOrange 2 Factor Authentication 5.4.22 WP-Members 3.3.6
 * Can you replicate this error on your side?
 * Thank you,
    Andrei

 * Hi @andrei0luca,
 * Thank you for reaching out to us.
 * We tried to replicate the issue on our end. It is working fine with the WP-Members.
   The issue is also not related to the PHP or plugin version. Probably it should
   be some other plugin that is creating a conflict. Our experts are looking into
   it.
 * We can also look into it over the screen share in your environment. Can you please
   raise a support ticket using the plugin so that our developers can directly look
   into it? You can also send a query using the following link: [Contact Us  ](https://www.miniorange.com/contact)

 * Hi guys,
 * Currently undergoing some debugging, trying to find the source of this error 
   in the error_log.
 * So far **it’s not the theme** and **it’s not another plugin** since I deleted
   all plugins except miniOrange 2FA and WP-Members.
 * Hopefully soon I will come back with an update.
 * Thank you for your support,
    Andrei

 * We are looking forward to your reply on the ticket or support query in the plugin.
   For the time being, I will close this ticket and mark this as resolved.
