Error 500 al actualizar a Joomla 3.8  

Hola Adrián.

las lineas que muestras en la captura son de fecha 7 de julio, las que necesitaríamos ver son las ultimas de fecha de hoy.

¿Cómo y desde dónde reinstalo mi copia de seguridad?

Tranquilo que puedes restaurarla fácilmente con al herramienta superbackup que encontraras en tu Área de clientes.

Dispones de copias de los últimos 30 días que puedes restaurar o incluso guardarlas en tu equipo.

Lo ideal es que tu mismo aprendas a hacerlo para que en casos de emergencia, puedes solucionarlo en cuestión de minutos.

No es difícil ya verás 🙂
Vamos paso a paso:

Primero, ve a tu área de clientes -> webempresa.com/areacliente.php

Luego, ve a la pestaña "Hosting" -> SuperBackups

A continuación, elige una copia del día anterior de dónde tu web funcionaba correctamente

Por último, de las tres opciones, selecciona estas dos:

1º Desde la pestaña "Restauración parcial" > pulsa en el botón azul "Restaurar el directorio public_html completo"

2º Desde la pestaña "Restauración bases de datos" > selecciona la base de datos que utiliza tu instalación

Con ello, tu web quedará restaurara a la copia que previamente has elegido 🙂

Hola Pepe,

He ingresado a mi área de cliente, luego a SuperBackups y he notado que sólo existe la dirección partidodebolivar.com

No me queda claro si el backup restaura toda mi cuenta partidod (+ todos los sitios contenidos), o sólo la web www.cfp402bolivar.com.ar que en concreto al actualizarla a Joomla 3.8 generó el error 500.

El resto de los sitios que tengo dentro de mi cuenta están funcionando correctamente, con Joomla 3.7.5
Como se sugiere, antes de instalar un pluging o realizar una actualización, realicé un backup de mi sitio www.cfp402bolivar.com.ar con Akkeba Backup, sólo que esta vez no lo he bajado a mi pc, y está en el directorio que por defecto utiliza Akkeba Backup. Lamentablemente no recuerdo la carpeta. Si tengo en mi pc, copias de meses anteriores, por ejemplo site-cfp402bolivar.partidodebolivar.com-20170731-130457.jpa

Adjunto detalles de error.log

Hola Adrian.

No me queda claro si el backup restaura toda mi cuenta partidod
Si, restaura toda tu cuenta de hosting, si solo quieres restaurar una de ellas elije la opción " Restauración Parcial "

.- En la opción buscar añade la carpeta donde estaba instalada tu web.

Recuerda que tienes que restaurar la BD de esa instalación y que tanto los ficheros con la BD tiene que ser de la misma fecha.

Si ves que tienes problemas para restaurar la copia, manda un ticket a soporte indicando que tienes problemas para restaurar una copia y les pones el dominio que quieres restaurar y la fecha a la que quieres que sea restaurada.

Un saludo
