Ralentiza mucho mi web, he intentado optimizarlo desactivando las funciones que no considero esenciales y nada... Si tuviese otras alternativas lo sustituiría pero ahora mismo es irremplazable.
Jetpack is a great plugin that shows stats of your site and when your site encounters an error like down it notifies you by an email and it is a great feature.
It's unbelievable how many so helpful functions could be included in a single package. Very appreciate your work.
