First Time using Envoyer , problem with 4.2

Hi guys,

From Three days ago , I was trying to solve my problem but I cannot

I deployed my project to my server and it installed but when I'm trying to open it by browser (Blank Page ) and the permissions of files is 755 and 777 for storge folder.

I use a global scope with all my models which will add to query (where user_id = Auth::user()->id_user) , in a boot function.

I cannot to log in an application and when I go to login page , blank page .

When I go to error_log in public folder I found some errors I think it related to model and global scope , this is the error: http://paste.ofcode.org/AfY3QBzjHViMnDqVtGSNLz

and this is one of models code http://paste.ofcode.org/32XivRmERKe9vUtabRArQ9q

Note: The application works fine. before I use Envoyer and it sames code. no diffrente.

so , I need for your helping , I googled for three days.

thanks

Majeed
