PHP Fatal error WP2FA\Core\wp_salt()

Hello Artem Komarov!

I am really sorry to hear about this experience. This is actually the first time seeing this so I would like a few more details just to better understand this:

Before answering the questions below regarding the error, please note that if you still cannot access the website, you can manually deactivate the plugin to regain access. The process is straightforward – all you need to do is rename the plugin’s folder. You can find more information about this process here: manually disable WordPress plugins with no wp-admin access.

#1 Once you regain access, can you let us know when this error started to happen? Was it a fresh installation, or you updated the plugin from an older version? I am not sure what this actually describes “crash on POST /wp/wp-login.php?action=validate_2fa”

#2 Are there any specific steps in reproducing this that you can share with us? Some screenshots can also be helpful; just to get a better picture of how this error affects the plugin/site. (please make sure you hide/blur any sensitive info from the images if you share any with us here, on the forums)

#3 Have you tried removing the plugin and reinstalling it afresh? Speaking of this, we just released version 2.7.0 moments ago, and I wonder if the error still reproduces if you try updating to this or installing this new version afresh.

You can ensure a full removal of plugin and all it’s files and database files by activating this before removing the plugin – see reference here

Looking forward to hearing back from you on this with as many details as possible.
