Error 500 al activar commom plugin

Hola buenas noches, active common plugin y se cerro admin, luego no pude ingresar mas y me indica error 500. ahora esto volviendo a cargar todo de nuevo. Alguna sugerencia?

@materialesanfra You can avoid having to reload the phplist code by renaming the plugin file so that phplist does not recognise it

lists/admin/plugins/CommonPlugin.php

to lists/admin/plugins/CommonPlugin.php.xxx

Look in the php or web server error logs for any error reported.
