Hello,

5xx errors are usually caused due to server misconfiguration or other server issues.

Can you please share the website error log with us?

Having the error log file will give a clear idea of why this might be happening.

You can follow this guide to enable debugging in WordPress
https://wordpress.org/support/article/debugging-in-wordpress/ or you can get in touch with your web host, they will help you locate the log file.

Looking forward to helping you.

Hello,

Please check if PHP values are not too low to handle the processes.

You can check that by going to WordPress dashboard > Tools > Site Health > Info tab > Server

If the values are low, please contact your web host and ask them to set the following values:

PHP Memory Limit: 512M
Max input time: 150
PHP time limit: 120
PHP max input variables: 1000

You may get in touch with your web host and ask them to set the above values.

If the issue persists, then please follow this troubleshooting guide:

Let us know how that goes.

Thank you.

Hello,

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:

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):

We really look forward to helping you.
