I’m leaning now towards suspecting the register page in buddypress. It has a text, and below that a form element, and within the form there are two sections, div. These divs have their respective sizes but these sizes are not inherited (or whatever it’s called) up to the form, so the form appears with no vertical extension.
This leads to that when the right sidebar moves to a relative position, its div will cover the form, and it becomes impossible to click the fields to type.
I tried now generating a page with a form, and it displays properly. So I’m convinced the solution is by editing something in the buddypress code that generated the registration page.
Hi, the theme is Bootstrap based and when the CSS shifts to relative vertical position at screen width <768 px then the register page is picked up at the wrong height. The text above the form is counted as the page height, and the form is being ignored. To fix it, one would have to change whatever it is that specifies the div height for the register page, and I still haven’t found that.
