Assertion failed ONIXCodelistItemDAO


I just installed OMP 3.1.1. When I try to “Add publication format” in the Production phase a new window is opened. But in that window the drop-down menu “Publication Format” is empty.

I have checked the php error log and foudn this entry:

PHP Warning: assert(): Assertion failed in C:\Apache24\htdocs\omp-3.1.1\classes\codelist\ on line 91

Any idea how to solve this?

Hi @primozs,

Do you have XSL support in your PHP setup?
