Hi Nikko,
It took some time but I now know who is interfering with the theme, it is the plugin duplicate page, Version 4.5.2 by mndpsingh287
We use the plugin often so we would like it to be co-working with your theme.
Best wishes,
Hans Woutersen
I didn’t need any support since the product worked fine and is a user friendly theme. Now, after two and a half years critical errors appear, I hope you can give me advise although the support license is expired
best wishes
Hans Woutersen
