After upgrade to LISE 1.5.4 i see following error in Items list instead of
items:

unable to write file
C:\Apache24\htdocs\prototypes\app\wet\tmp\templates_c\0819a6ff8ec9a47f743cf61e4030d8247c3ee89a_0.lisetemplate.fielddefs;LISEProjects:LISE;type;list.Dropdown.tpl.php

And editing a Field Definition or to create new item gives an 500 Error.
