[resolved] fopen(): open_basedir restriction in effect. File(/dev/null) is not within the allowed

Hello,
I have an isconfig 3.1.12 installation

I browsed the forum and found the same problem several times but the solutions that have been tried do not work

I work with the Laravel framework to avoid giving access from the web to uploaded files, I store them in a directory outside the public
On my local server and dev everything works fine
On the production server which works with ispconfig I have this error message
fopen (): open_basedir restriction in effect. File (/ dev / null) is not within the allowed path (s)

At the vhost level I have some modifications, not all of them correspond to my problem:

Code:

DocumentRoot "/var/www/clients/client12/web19/web/public"
Header always set Strict-Transport-Security "max-age = 31536000; includeSubDomains"
Header always append X-Frame-Options SAMEORIGIN
Header edit Set-Cookie ^ (. *) $ $ 1; HttpOnly; Secure
Header set X-XSS-Protection "1; mode = block"
Header set X-Content-Type-Options nosniff

you can see I'm pointing the web directory to public
my tree

web /
framework directories
public / (the public directory)
ged / (the file storage directory)
ged / tmp / (a temporary directory which I use to create large pdf)​

for the storage part no problem I can upload pdf, word, Excel from a form ... and I can also call them and display / download them.

My problem is in the generation of pdf I need to generate large pdf (700 to 800 pages) for that I chose a multi process approach. I create several php processes which each generate a part of the final pdf for me each pdf is stored in the directory tmp / {user_id} / {ask_id}
once all the chapters are created i merge them into a single file which is stored directly in ged. the directories and file in tmp are then deleted.

I modified open_basedir PHP:

Code:

/var/www/clients/client12/web19/web:/var/www/clients/client12/web19/web/ged:/var/www/clients/client12/web19/web/ged/tmp:/var/www/clients/client12/web19/private:/var/www/clients/client12/web19/tmp:/var/www/c12.app7.nc/web:/var/www/c12.app7.nc/web/ged:/var/www/c12.app7.nc/web/ged/temp:/srv/www/c12.app7.nc/web:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/dev/random:/dev/urandom

but nothing to do that does not give me access to this damn directory rights to the directory have been verified and having tried everything I even restart the server completely (without much conviction ...)

Thanks for your help

 

Dear Till,
I do not thank you, I am never felt alone until after reading your answer
I misinterpreted my logs. I thought the information was generic and I did not add the /dev/null
Thank you so much

It is done with /dev/null my script can generate my pdf.
I hope my stupidity will help someone else

PS : sorry for my average english
