Dictionary problem

Hey, whe use the V2.3 of OCS and we have the problem that new created categories in the dictionary are not shown in pulldown menues.

So when i try to send a new foundet software to an existing category, the category is not shown in the menu choices. If i try to create a knew category i get errot, that the category allready exists.

So at this point it is not possible for us to manage the software in the dictionary.

In the Apache error.log the following lines are shown:
