As far as I know there has been no problem detected running v.6.6.6.
@jogeta you need to report the error to your hosting provider, because something seems to be wrong with the upgrade tool.
According to your screenshot, those errors are not coming from b2evolution but from the upgrade tool. Also, having version 6.6.6 working properly is another hint to know that the error is not in b2evolution.
@jogeta those PHP extensions are mandatory for b2evolution to work. You should ask your hosting provider for help installing/enabling the extensions.
Btw, if you're upgrading from 6.6.6 to 6.6.7, is the 6.6.6 version working properly on that server?
