Cuando no es posible crear las tablas de redirecciones en el plugin de SEO Rank Math desde el escritorio de WordPress solemos obtener algún error similar al siguiente:

Y la única forma posible que hemos encontrato para solucionar es ejecutar la creación de las 2 tablas que nos faltan de forma manual desde consola Mysql o MariaDB o también desde el PHPmyadmin de tu panel de control Plesk o Cpanel.

Puedes ejecutar este código SQL cambiando el prefijo de tu base de datos por el que tengas en tu instalación. Hemos puesto wpdirecto_ para que sea fácil de localizar y cambiar.
