1. So after buying a lifetime subscription to Toolset, and now realising that there are conflicts with my theme (of which I'm not sure how to fix), are you not willing to help find out why I'm unable to use it?
I am sorry, but there are no conflicts.
This is, as stated and demonstrated, even happening without inserting any View at all.
Just insert the Text "HERE" into that "widget" and you will see it in the "Widget like area" on the bottom left, very low, not properly visible, with a scroll.
I will help you solve every issue of Toolset, but this is not a Toolset issue, as you can see even normal content is not displayed fine, correct?
I tested this, on your install, as previously mentioned.
2. To be honest, I'm not sure if it is a theme issue, there is still coding for infinite scrolling still showing and pagination for that view has been turned off (see screenshot, I hope it attached this time. If not, have a look at the code that is being spat out for the view:
If the View's pagination is turned off, there will be no pagination or infinite Scroll feature on the content of that View.
You can see this when you insert this View in a normal Page and view that page.
If Scroll/pagination is off, it will just display all results.
If it's on, it will paginate your results with the effect you chose.
I added the View to this Test Page, for the demonstration of this feature:
hidden link
You can enable/disable pagination in the View now and will see it working on the Front End.
I do not know what "hooks" you used to add those "widgets", this is not visible in the Screenshot you added to the last post.
Also, I mentioned, this is not how you register widgetized areas.
I passed you the DOC where it's explained hot to do this, and there you would use native Widgets or our Toolset Widgets (there are 2 of them, for Views)
Please correct me if I overlook something, but the issue you describe is not related to Toolset, as it's happening with very simple, minimal Text as well.
