Hi Frank,
If the plugin isn’t working for a specific theme I’d recommend to create a support thread to see if / how I can help.
Giving a 1-star rating because the plugin doesn’t seem to work on your specific theme isn’t really considered a good practice since every theme is different and plugin(s / authors) simply can’t test / support all of them.
If you can open a support thread and elaborate what isn’t working for you I will try to help you fix this for your theme.
Have a great day!
