Just wanted to let you know i found the cause of the error and maybe this solution can help others.
Instead of seeding and publishing via the Apex screens i used a script to seed and publish, the script uses the procedure "wwv_flow_translation_utilities.seed_and_publish".
After executing this script there was a more detailed error where i could work on, the error was "ORA-20001: Error during execution of wwv_flow_copy: WWV_FLOW_STEP_ITEMS >> ORA-02291: Integriteitsbeperking (APEX_040200.WWV_FLOW_STEP_ITEMS_PLUG_FK) is geschonden - bovenliggende sleutel is niet gevonden."
After digging into the items and plugs i found an item in application 137 wich was linked to a region of another application 136.
Now how this happened is still a question mark, but changing the region of that item to a region of the same application solved this issue.
I had to change it by using the "Edit all" function because going to the detail of that item made apex go in error mode.
