Menu problem on mobile version of my website

Hi, @zohim1

1. You can use the second layout to see the Add to cart button on the mobile version: https://prnt.sc/vzfsw3
Or using this css code. Add in the css section of Theme Options and remember to take the backup when you update the theme

.armania-mobile-style-01.single-product .entry-summary .added_to_cart, .armania-mobile-style-01.single-product .entry-summary .product-buy-now, .armania-mobile-style-01.single-product .entry-summary .single_add_to_cart_button{
-webkit-transform: translateY(-60px);
-moz-transform: translateY(-60px);
-ms-transform: translateY(-60px);
-o-transform: translateY(-60px);
transform: translateY(-60px);
}

2. We are unable to check all plugins and get the configuration. However, the theme supports plugin WPML. This is the paid plugin and translates automatically your site into the languages you want
