Auditoria de sitio Wrodpress+ Woocommerce hosteado en Godaddy con problemas con conexion a la base de datos

Tengo un sitio desarrollado en Wordpress+ Woocommerce, funcional hace 3 años, con cambio de theme y customizacion hace 6 meses, que comenzo hace 20 dias a dar errores de conexion con la base de datos.

Necesito alguien pueda analizarlo, encontrar los errores y corregirlos.

Van algunos ejemplos de los errores.
