When I visit my contact page, it immediately jumps to the form halfway down the page, while I want to start at the top of the page. How to prevent from jumping?
Already tried add_filter( 'gform_confirmation_anchor', '__return_false' ); and add_filter( 'gform_confirmation_anchor_5', '__return_false' ); but this didn’t solve the issue.
Gravity Forms will not do that to your page. You don’t need to use gform_confirmation_anchor (that only applies when a form is submitted, to set where the page is reloaded after the page or form submission.)
It looks like a conflict on your site, or some invalid HTML. I recommend checking for conflicts first, using these steps:
You have tried this with a new theme like Twenty Twenty, in addition to no other plugins being active? My guess would have been a conflict with your theme or page builder.
