@rasolis I renamed the older widgets to Front Page 1, 2, 3 etc since that’s the direction the newer themes are being developed (Here and StudioPress as well).
Everything still works the same, but due to the way I renamed the widgets you’ll need to drag the widgets into the new renamed widget locations.
Here are the old widget location names – https://appfinite.com/img/optimal-widgets.jpg
And here are the newer Widget location names (they’re all labeled Front Page 1, 2, 3, etc) – https://appfinite.com/img/optimal-widgets-2.jpg
Once I installed the new version of Optimal, it only took a few seconds to re-drag the old widgets into the newer widget locations. They should show up in your inactive widget locations in the same order that they were positioned in the previous version of the theme. So all you would need to do is drag each one over to the new locations.
