WP offline "file not found"

Hallo!
Ich habe hier ein dringendes Problem.
Meine Seite ist seit gestern offline und ich weiß nicht warum.
Beim Aufrufen der Domain c r o s s t o u r s . a t kommt nur "file not found".
Leider bin ich zu neu um zu wissen wo der Fehler liegen könnte.
Meines Wissens wird als erster die
index.php geladen:
<?php
/**
* Front to the WordPress application. This file doesn't do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/


/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define('WP_USE_THEMES', true);


/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

welche dann nur die wp-blog-header.php aufruft
welche dann wiederum nur die wp-load.php und die template-loader.php aufruft ....

Was läuft hier schief?
Bitte um dringende Hilfe ...
lg

 

Ich habe lediglich in der meta.php einen Text geändert .. ansonsten nichts .... das kann ja nicht der Grund sein.
WP ist ja nicht einmal geladen ... der WP-admin Bereich ist auch nicht erreichbar ...
Am Hosting-Provider kann es nicht liegen, da ich gewisse Bilder die im selben Ordner liegen über im Browser über die Domain aufrufen kann.
Hier kann es sich nur um ein kleines Problem handeln

 

Zur Info, die Text-Änderung die ich gemacht habe, habe ich danach auf Funktion geprüft und alles war in Ordnung. hmmm

Ich habe jetzt eine Wiederherstellung der kompletten Daten von vor 2 Tagen veranlasst.
Leider hat das das Problem nicht gelöst und somit kann ich die Frage ob was an der Seite geändert wurde, mit NEIN beantworten.

Gute Frage was das jetzt noch sein kann ...?
Jemand eine Idee?

 

Folgende Logs habe ich von der Hostingsite:

Ja Seite ist nach 36h wieder online aber keine weiß warum und der Hosting Provider stellt sich dumm. Diesen Freitag wieder das selbe Problem (wieder ein Freitag und fast die selbe Zeit) ... nach
Anruf in der Hosting-Bude haben die dann auf PHP7 aktualisiert und fragten ob die Seite jetzt ginge.... das kanns ja nicht gewesen sein ... ich schätze mal, dass deren Neustart das Problem kurzfristig löste ... aber was bedeuten die Fehlermeldungen?
