I have a problem filling in the table of support ticket. That's why I sent all the data to your email
I get Invalid Host name warning

The reason why you could not create a ticekt is because tried to submit the Control Panel login page as FTP hostname.

I managed to solve it. The add-on needed an update to comply with the newer versions.

Thanks Tim
