Solucionado!!!

Muchisimas graciasss.

Hola, hace unos dias realice varias actualizaciones desde 1&1 y me encontré con esta serie de errores..

Strict Standards: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead in /homepages/7/d393648789/htdocs/piwigo/admin/intro.php on line 116
