Tengo un problema al hace la copia de seguridad de mi web. Si cambio el tema no me sale el error. A que se puede deber esto??? La que tengo activa funciona perfectamente pero cuando hago una copia de la base de datos y los archivos y los subo a local para probarlos el tema sale todo descolocado y sale ese error con muchas más líneas.

Tiene algo que ver con el tema?
