Do I have permission to disable all active plugins, as I am not entirely sure how this happening. I am also not able to recreate it on my end even when duplicating all your settings.
I’ve just disabled all active plugins except for BB and the pages are now displaying as intended.
Therefore, can you go through each of your plugins enabling them one at a time and see which one is causing the problem. I understand this is a tedious task, but this is a surefire method of finding the culprit.
I’ve kept the plugins disabled, so you can see that the pages are now aligned correctly.
I thought problem was that I was using bb shortcode in footer widget, so I turned off footer widgets in customizer and added this code to functions file, as in this post thread
// Add global footer to footer
add_action('fl_after_content', 'global_footer');
function global_footer(){
echo do_shortcode('[fl_builder_insert_layout slug="global-footer"]');
};
