Página blanca a veces cuando carga PS 1.7.5.1

[RicRey]

Me doy cuenta que a veces ocurren un error raro cuando el sitio carga, me sale una pantalla blanca "ocurre de manera aleatoria y no siempre"

tambien cuando carga bien que es la mayoría de veces sale una advertencia tal vez alguien sepa que es?
