Another possibility for this warning  and  most likely  problems with app behavior  is that the original author of the app relied on session auto start being on  defaults to off  If you don t want to mess with the code and just need it to work  you can always change php configuration and restart php-fpm  if this is a web app    etc php d my-new-file ini   session auto start   1   This is correct for CentOS 8  adjust for your OS packaging
