At this moment we have troubles with PHP 8
We will return on short notice. 
We worked with an old version op PHP 4
Support for that is not free
Last year support cost 29,88 per year and now it is raised to 29,88 per month. 
That is a raise of 1200 % 
The goose will be very expensive when we have to pay so much for support. There fore I changed te PHP to 8.5. In the first days that worked pretty well but now it stops working.
