[Plugin: WooCommerce – excelling eCommerce] Featured Image, Store categories, & Variable attribu

when i try to set a feature image to any product it stays on “saving..” never goes to done

if i make a product a variable product, i can add the attributes, but then i try to add the variation and that wont load, upon clicking the variations button, its like the button is linked to nothing

same thing happens to add a category or remove the featured image from the category, nothing happens.

could this be a server issue? or theme issue? or its not compatible with my version of word-press?

theme:
https://themeforest.net/item/bellissima-woocommerce-wordpress-template-/2574182?WT.ac=category_thumb&WT.seg_1=category_thumb&WT.z_author=Unifato

it says compatible with woocommerce 1.4.2, but i have 1.6 where cna i get 1.4.2
