Hello Michel, thank you for the link.
I cant seem to update the Theme (Airi Pro) even though it say that the plugic Airi Pro is active.
Do you get some error when you are trying to update the Airi Pro plugin?
how do I determine which demo site I used in the beginning
I checked your home page but it seems to be quite customized, so I’m not sure which demo was imported initially.
Can I switch demo themes after the fact?
You can’t switch demos easily once you have imported one. But you can try to create a full site backup (make sure that you know how to restore it), delete site content, and import another demo.
Please feel free to ask any other questions that you might have.
Kind Regards, Roman.
