session_start(): Session data file is not created by your uid

Question

I want to store the created sessions in a directory above the root, except when I use any of the following:

    session_save_path($_SERVER[\'DOCUMENT_ROOT\']         


        

Answer 1

Editing config/config.yml and replacing save_path:

session:
    save_path: '/tmp'

Answer 2

I could be that your Session file was created by another user (well UID), try (re)moving the session file(s) from your temp dir something like /var/tmp

Answer 3

For lampp users,
- go to /opt/lampp/temp/
- delete session file, and test again

After testing again,
If error message "Wrong permissions on configuration file, should not be world writable!" shows,
Run the following at terminal:
sudo chmod 755 /opt/lampp/phpmyadmin/config.inc.php

That worked for me ...

Answer 4

On Ubuntu within Windows 10 , my php user is the default user I create for the first install, I dont know why because the etc/apache2/envvars is not configured like that.

Nevermind, I change it for fix it quickly and now, it works.

export APACHE_RUN_USER=rudak
export APACHE_RUN_GROUP=rudak

Answer 5

What worked for me, could work for you as well.

It looks like something went wrong with the session. Open the browser's DevTools and delete all Sessioncookies.

Answer 6

PHP requires session file to be owned by the user running PHP.

Then just run chown -R www-data:www-data /var/www/storage/sessions/ to own session folder and files by your PHP user (www-data:www-data are your PHP user and group separated by :).

You can use PHP method get_current_user() or run in bash php -i | grep user and find your user running PHP there.
