I have updated the Illdy theme to latest version (2.1.8) and Wordpress to latest version (5.6.1 ) and the home page now doesnt scroll. The scroll bar is missing on the side or the browsers now and it wont scroll down past the jumbotron section. We have the about us, services, testimonials, full width and contact us sections active but cant see any as the page doesn’t scroll.
I worked out the issue is related to Popup Maker plugin. Once disabled the site starts working correctly again.
Nice to hear you found the root of the problem
