3.0 is in beta – so we don’t support it via the forums.
You are welcome to ask for a copy and take it for a spin – but you do so at your own risk. It’s essentially an advanced preview aimed primarily at developers/designers. We hope of course to receive valuable feedback from our testers and in turn they get to look at the code and plan ahead accordingly so they can deliver the best service to their customers, update plugins etc.
The officially supported version (2.x) doesn’t work with current php and wordpress versions. At least from what I have tried in the free version.
We can definitely try to help with the current version – what are the specific issues you are seeing?
