The add to cart (or whatever) button is not present on mobile or desktop. To eliminate doubt, I’ve recorded my mobile screen for your review: View error on YouTube
I have installed a staging site at http://thedelivery.store/. (You previously stated the site doesn’t work, but it does; I had a 3-hour meeting with them and we were able to visit, edit and everything. I also checked uptime services like Is My Site Down or is it Just Me? and it’s completely up. Besides, had it only been my cache, no automated actions, such as checkout, would have worked.)
Please advise on how to ensure people can add food to their delivery order. Thanks!
P.S.
For kicks, I took a look at foodbook/assets/css/app.css?ver=1.0.0 and reviewed .fb_card and textarea.fb_input_style. I think that using fb in CSS could possibly conflict w/ other CSS that may use Facebook-related CSS, but that’s just an opinion.
