Hi! On my installation I was having some troubles with the admin panel that showed a blank page, but then I solved it. Now when I loggin I can see my dashboard and use all the buttons except fop the¨Users¨ button because it shows a blank page too.

The permissions are the same for fop2settings.db (apache:apache) and for /var/www/html/fop2.

Hello! I saw on the logging files an error about mod_ssl, in my case I solved it this way:

• Confirm/Add the port tcp 4445
  #firewall-cmd --zone=public --add-port=4445/tcp --permanent
• Here on the log was a line showing something like "mod_ssl" so...
  #vim /var/log/httpd/error_log
  #dnf install mod_ssl
  #systemctl restart httpd

When I tried to configure my user panel from the manager i noticed that if i click on the button "buttons" all the buttons are erased

Solución:
Abrir el puerto 4445 en el propio servidor

Hola cuento con un servidor CentOS con FOP2 que funciona correctamente actualmente en uso y se conecta a nuestro Asterisk, por otro lado al querer cambiar de SO en otro servidor (Rocky Linux) instalamos una versión demo de FOP2, ya adquirimos otra licencia y la de mantenimiento(Aun no la usamos). El panel de /fop2/admin trabaja bien, creamos un usuario ahí que ya es una extensión en nuestro Asterisk pero al querer acceder al portal /fop2 se queda en la pantalla de Connecting to server, attempt number, System is not available right now y en ningun momento nos arroja el login.
