I just installed the The Leader 2.5 on a fresh install of WordPress 4.9.8. When I try to add a new header image for the site under Theme Options > Header all I see is a blank space. Does anyone have an idea as to what might be going wrong here?
Problem is related to the PHP version that you use. TheLeader has compatibility issues with PHP 7.x.
We can get you the refund for TheLeader theme and would like to draw your attention to XStore theme https://themeforest.net/item/xstore-responsive-woocommerce-theme/15780546 . XStore is the more advanced theme that is compatible with PHP 7.x and also WooCommerce 3.4.x. Besides XStore includes a number of cool plugins and has a lot of versions.
We have given you the refund. Now you can proceed with the XStore theme purchase.
Don’t forget to register XStore purchase code in your account area on our site to be able to post questions on the XStore support forum.
