Hi GeurKleur19e
Apologies for any inconvenience caused.
We've just checked those functionalities on our server, and they are working correctly.
Which version of ATUM are you using?
Can you check if anything is saved in your PHP error log when you create a PO or activate a license?
If you don't know how to activate the error log, please read this.
FYI, the only available support channels are this Forum and Ticksy for private tickets.
Best Regards,
José Andrés
