[Solved] Zextras Admin is not visible

Hi,

I have installed Zextras suite on Zimbra 8.8.15. The installation completed successfully, but unfortunately the Zextras Admin panel is not always visible on the Zimbra Admin site. It appeared a couple of times and I was able to configure some services, but then it disappeared and I needed to reboot the server, sometimes more than once, to have it back.

Is there something I can do to reactivate it, when it is not visible, without rebooting the server. Installation is on a single server. Zextras suite is the latest 3.10

Thank you,

Andrea
