This is a strange problem.
FreePBX 2.9.0.12 Distro. New install on new superMicro box.
I did a backup from the customers existing system which is also running FreePBX 2.9.0.12 Distro and restored it on the new SuperMicro box.
the problem is that the link in the upper left corner of the page that shows the user that is logged in and a link to logout is now missing.
It should have the following HTML
Logged in: mousty (Logout)
but it has this instead.
Clearly the the above HTML has to be generated at login time to get the logged in user name.
Note: This was an old FreePBX 2.6 system that the team at Schmooze help me upgrade. They did a great job as usual but for some reason the link is missing.
