I got this error from my NGINX server when I am running a script in Prestashop. I think this is something I can solve in the NGINX configuration or something, but I need some help to tell me what to do.

Warning: file_exists(): open_basedir restriction in effect. 
File(/www/wwwroot/panel_ssl_site/../app/etc/env.php) is not within 
the allowed path(s): (/www/wwwroot/panel_ssl_site/) in
/www/wwwroot/panel_ssl_site/bridge_i15GpcsW.php on line 832

• How can I solve this?

Thanks,

Petter

What is PHP open_basedir

It limits the files that can be accessed by PHP to the specified directory-tree, including the file itself. This directive is NOT affected by whether Safe Mode is turned On or Off.

When a script tries to access the file system, for example using include, or fopen(), the location of the file is checked. When the file is outside the specified directory-tree, PHP will refuse to access it. All symbolic links are resolved, so it's not possible to avoid this restriction with a symlink. If the file doesn't exist then the symlink couldn't be resolved and the filename is compared to (a resolved) open_basedir.

open_basedir can affect more than just filesystem functions; for example if MySQL is configured to use mysqlnd drivers, LOAD DATA INFILE will be affected by open_basedir. Much of the extended functionality of PHP uses open_basedir in this way.

The special value . indicates that the working directory of the script will be used as the base-directory. This is, however, a little dangerous as the working directory of the script can easily be changed with chdir().

In httpd.conf, open_basedir can be turned off (e.g. for some virtual hosts) the same way as any other configuration directive with "php_admin_value open_basedir none".

Under Windows, separate the directories with a semicolon. On all other systems, separate the directories with a colon. As an Apache module, open_basedir paths from parent directories are now automatically inherited.

The restriction specified with open_basedir is a directory name, not a prefix.

The default is to allow all files to be opened.

Reference PHP.NET, 1

Conclusion

You have used open_basedir, and you did not update the path. Additionally, i believe you that this Question should be asked on Superuser, as the evidence tells me that you are not using a Business Related environment.

php.ini (on Debian 10)

; open_basedir, if set, limits all file operations to the defined directory
; and below.  This directive makes most sense if used in a per-directory
; or per-virtualhost web server configuration file.
; Note: disables the realpath cache
; http://php.net/open-basedir
;open_basedir =

That example, from above, is the DEFAULT setting on Debian 10 which is usually also the default on php.net. Which means you have changed it either manually. Or what I believe, since the path names included "panel_ssl_site" is that I think you're using an Admin-Panel and this leads to, that this Question goes into OFF-TOPIC. However, every Admin panel should be able to change this setting too, See regarding Reference StackOverflow to the same issue
