I was using the Graphene theme without any problem, before I shifted my website hosting to a different server; after that, I am not able to install or use the Graphene theme; the message says the Graphene theme is installed but broker, and the Stylesheet is missing. Now I am not able to access it from my dashboard. Should I do it from the cpanel on the server? What should I do over there to uninstall it over there? Or is there some way to access it from the Dashboard itself.
