Hello! I installed Upfront Builder succesfully. When I go to Upfront > Builder in WP Admin, I get the option to create an own theme. When I give it a name and click on the green button "Start Building", I'm redirected to the following url: http://profits.crony.nl/create_new/crony-profits
this takes a while an then I redirected to a 404 error page and there is no theme added. I don't know why Upfront is doing this
Anyone can help?
