Cannot Login after reboot

After upgrading Owncloud to 8.2.4 I am having a strange issue. The issue is that every time the server is rebooted none of my clients (except the admin account) can login into Owncloud. When a client tries to login, the message "Wrong password. Reset it?" appears. I have went into the user dashboard of ClearOS and reset to password without any success.
The only way I can get Owncloud to work is to uninstall/install and it will work until the next reboot.
So far, Owncloud running under ClearOS has been very unreliable.

Any suggestions??
