cannot open chronoforms 4 backend

Hi
On this website chronoforms 4 is running:
http://www.trachtenvereinigung.ch/dienstleistungen/marktplatz.html
I cannot open the chronoform backend, so I installed the new version.
Now I see, that I have running version 4 and 6 on my Joomla.
Can I update/migrate version 4?
Thanks and best regards
Aschi

Hi Aschi,

There is no automatic upgrade path from CFv4 to CFv6 - you would need to rebuild the forms.

What exactly is the problem with CFV4?

Hi Bob
Thanks for your answer!
The problem with CFV4 is, that when I try to open the component in the backend, I get this url:
http://www.trachtenvereinigung.ch/administrator/index.php?option=com_chronoforms
but the page is blank.
Best regards
Aschi

Hi Aschi,

A blank page is often a sign of a PHP error, please try setting Site Error Reporting to Maximum temporarily and see if you get a more helpful message.

Hi Bob
