Please, provide your site admin access (insert the site credentials into the Private content block under the message area) and confirm the permission for plugin deactivation, switching to the parent or default theme. As soon as we complete the testing we will enable all back, however, the site would be without plugins for 15-20 min. You would better make the full backup of your site.
Please make the full backup of your site and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.
