Hi Roland…not sure why you posted this in the “Suggestions” forum category, but I moved it to Celestial Reloaded.
Anyway, with Dynamic Widgets, when you did your settings, did you click the text link “No” (under Quick Settings) at the top part of the dynamic widgets settings to not show everywhere then selected the page(s) where you want it to show?
As a side note, an alternative to Dynamic Widgets (which does have a learning curve) is a plugin called Display Widgets, which is much easier to use if you don’t need a lot of complex publishing of widgets. If you use Jetpack, they also have a built-in widget visibility feature as well.
Ah. Turns out I did not use the “quick settings” at all. I just went straight to the pages and posts tabs (which were all set to “No” so it seems a bit . . . redundant but either way you got it under control for me.
