I’ve searched and tried a number of the fixes described in other posts for getting rid of this – CSS, removing the page title, etc. – and none of them work.
I’m using Elementor Pro, canvas layout, and have pretty well turned off everything in GP.
Using Elementor to put a negative margin on the topmost section just makes a mess. Negative padding does nothing.
Please take a look at the cited page and see if you can figure out why.
