TimeTrex Time and Attendance

We upgraded to version 7.3.6 on May 7th. Yesterday, May 14th, and today, May 15th, we have been getting the following message:
WARNING: TimeTrex automatic upgrade has failed due to a system error! Please contact your TimeTrex administrator immediately to re-run the TimeTrex installer to correct the issue.
Our timetrex.php.ini file has installer_enabled=FALSE. It has been set to FALSE since we installed the latest version on May 7th. We are running timetrex on a Ubuntu 12.04 virtual server.

How do we get this message to disappear?
Thanks!

Here you go. Thanks!

Is the message still being displayed to you? If so, could send a more recent copy of the log file please?

No it is not. Why is that?

Not sure, perhaps it was just a temporary issue and its now working...
