I just installed 5.1.2.0 on a test instance on VMware Player and have noticed a couple of things to give feedback. Rather than create a new thread of each small item I'll just add to this one.
When Acquiring Locks on any asset I get the error message:
constant(): Couldn't find constant SQ_HIPO_ACQUIRE_LOCK_THRESHOLD
Clicking continue takes me to the initiating page and I seem to have the locks. A similar message appears when Committing a change:
constant(): Couldn't find constant SQ_HIPO_EDIT_STATUS_THRESHOLD
Looking on the HIPO Server Configuration screen shows all the field values still retain their PHP constant names. Screen shots:
