webiste crashed after installing rank math

Hello,

Thank you for contacting Rank Math, and sorry for any inconvenience caused.

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