Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Please disable Rank Math and reinstall the plugin.
Please let us know if that helps.
If not, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):
https://wordpress.org/plugins/wp-security-audit-log/
We really look forward to helping you.

Hello,
Unfortunately, the username/password still doesn’t work as you can see in the screenshot I added in the sensitive data section.
Please verify so we can continue debugging the issue.
Looking forward to helping you with this one.

Hello,
We are able to access your admin dashboard.
Since this is a fatal error, we need access to your FTP so we can revert back your website to a working state whenever we encounter the fatal error again while troubleshooting.
However, the FTP login you shared doesn’t work and we can’t connect to your server.
Please provide your FTP information in the following format:
Host:
Username:
Password:
Port:
Looking forward to helping you.

Hi Jemery
NEW tested ftp-login Data see box

Hello,
I’ve tried logging in to your FTP, but I’m still getting 530 Login incorrect. Could you please verify?
However, I’ve also checked your site, and it seems that you have a plugin 404 Monitor by Rank Math, which is possibly the issue as our 404 Monitor feature is not a separate plugin.
Also, there are Rank Math features (with outdated UI/design) available in your WordPress dashboard without even activating the Rank Math plugin.
Could you please try disabling that plugin and activate our plugin Rank Math SEO?
Let us know how this goes.
Thank you.
