Eroare opencart

Buna ziua si Hristos a inviat !
De curand ma confrunt cu urmatoarea eroare :

Warning: require_once(/home/..../public_html/jeepstore.eu/system/library/mail.php) [function.require-once]: failed to open stream: No such file or directory in /home/...../public_html/jeepstore.eu/system/startup.php on line 94

Fatal error: require_once() [function.require]: Failed opening required '/home/...../public_html/jeepstore.eu/system/library/mail.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/..../public_html/jeepstore.eu/system/startup.php on line 94

Am uploadat mail.php dar dupa dispar si am aceeasi problema.
Stiti ce-ar putea fi ?

Multumesc

Dispare fisierul? Daca da, contactati-va hosterul sa vedeti cum dispare.

Da, dispare fisierul .
Ce ar putea fi ?
Ar fi problema de la cei cu hostingul ?
Ce sa le zic ?

Multumesc

Ii intrebati cum dispare fisierul, cine/ce il sterge.
