It is the same exact sidebar which has only one widget in it: “posts”, where I specify exactly the same parameters.
The only difference; The home page has the sidebar inside a column (on the right side). The /events page has the sidebar as part of the selected layout (sidebar left) and it follows a calendar widget. Even when I removed the calendar, it stayed the same.
On the home page I tried to add “posts” from the Builder widgets directly to the column and I tried to add the sidebar widget (contaning “posts”) to the column. Both produced the same large font result. It is really annoying…..
And by the way, the is no CSS or H3 option in that “posts” widget.
