All StudioPress PRO themes will be supported by us so let us know if you find a problem with a supported theme.
In the case of a non-standard theme that we don’t support, you can add support for it yourself by adding code snippets at the appropriate Genesis Dambuster Hooks.
Alternatively, you can send us your theme and we can do this for you. If the work is trivial, like in the example given at the foot of the page linked to above, and then the work would not be chargeable. However, it your custom theme is more complex then we would give you an estimate of the work involved, typically $50-$100, and then you could decide whether or not to proceed.
