I use 5.3.9 on severals sites without any major problems.
Trying to install Pulse 5.3.9 on another server results in following problems:
- installation process shows 'hosting does not support sessions' (see screenshot)
- login page refreshes without being able to login
However, when checking php-info PHP shows that sessions are enabled (https://www.waermeverbund.ch/phpinfo.php)
Hosting company is unable to support.
Any hint what causes this problem?
