anytime a user logs into our Wiki they get the following error: \"This Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again.\" Even
If you are using NGINX + PHP-FPM the previous answers will likely not be of any assistance.
From the command line, run:
php-fpm -i|grep --color cookie_path
See what your cookie_path is, then stat the folder and ensure your php-fpm user has write access to it.
To resolve this issue using Nginx and Php-Fpm, I had to change my cookie_path from it's default of / (seriously, why would this be a default?) to /tmp.
After restarting nginx and php-fpm, it works perfectly.
