Sorry for the problem with installing the inspiration to a staging site. Normally, if you go into BoldGrid, click on Inspirations, and then install your chosen inspiration, then it would give you the choice to install over the active site OR as the staging site. IF you’re not seeing that, then you may have an old version of the software. Make sure you have the latest version and then try installing the inspiration again. If you continue to have a problem, make sure to provide us more information on your exact steps to duplicate the problem and include all versions of WordPress and BoldGrid plugins that you’re using.
If you have any further questions, please let us know.
