500 Internal Server Error - FatalErrorException

[Auto-Dress]

Hallo Zusammen!

Ich habe folgendes Problem:

Ich war ganz normal im Backend des Shops unterwegs als plötzlich eine leere weiße Seite erschien.
Seid dem kann ich mich nicht mehr über mein Admin Panel einloggen.

Um dem Problem auf den Grund zu gehen versetzte ich den Onlineshop in den Debug Modus und das kam dabei heraus:
 

Compile Error: Symfony\Component\Debug\DebugClassLoader::loadClass(): Failed opening required '/var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/vendor/composer/../../src/PrestaShopBundle/Controller/Admin/AttachementProductController.php' (include_path='/var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/tools/htmlpurifier/standalone:/var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/vendor/pear/pear_exception:/var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/vendor/pear/console_getopt:/var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/vendor/pear/pear-core-minimal/src:/var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/vendor/pear/archive_tar:.:/usr/share/php:/usr/share/pear')

Ich bin leider kein Informatiker und diese Meldung setzt mich vor eine schwere Aufgabe.

Gibt es einen "Profi" der mir evt. Hilfestellung geben könnte? Ich verstehe leider nicht genau was ich machen soll.

 

Schon mal vielen Dank im Voraus!

Existiert die Datei /var/www/vhosts/hosting101292.af98b.netcup.net/httpdocs/tumatsch-leder/src/PrestaShopBundle/Controller/Admin/AttachementProductController.php ? Wenn ja, stimmen die Berechtigungen, so daß der PHP-Prozeß darauf zugreifen kann?

Die Datei war nicht vorhanden. Warum auch immer!
Ich habe aus einem Backup die AttachementProductionController.php eingefügt und kann mich nun wieder einloggen.

Nun besteht allerdings das Problem das ich auf der Module Seite folgende Meldung angezeigt bekomme:
 

Cannot get catalog data, please try again later. Reason: Warning: curl_exec() has been disabled for security reasons
