When you export a form, if you keep the action blank it will not work as the JavaScript will return it as an error when it’s being submitted to the page itself.
This is not ideal as I sometimes have forms that submit to the current page. I usually export and write the PHP but this isn’t something I can fix without modifying the minified JavaScript that is exported. Instead I’ve had to not load the Webflow exported JavaScript and rewrite the interactions I want.
This isn’t ideal - as it’s a lot of work for such a tiny bug.
