I purchased Shopstore Pro version. 2 Plugins won’t install. They are Smart Variation Swatches for WooCommerce and WooCommerce Smart Popup Cart. I get the error “Download failed. cURL error 35: SSL connect error”. And my license won’t activate. Please advise.
SSL error related to server-side. if you face this problem again then please contact with hosting provider ..
