I’m using quite a few of plugins on the site, cause it works as a website and a point of sale too. I sent you user and pass so you can check it. Or if you prefer I can send you the whole list of plugins in use. The thing is we’ve been using the forms for long without any trouble, and they’re failing just since a week ago or so.
The template we use is Flatsome and the POS is Yith Point of Sale for Woocommerce.
