Thank you so much for purchasing our theme and contacting our support center.
Please, disable all plugins that are not related to our theme and provide us with your admin access. We will log in and check what is wrong there. You can leave only the following plugins that are required for our theme:
WoodMart core
WooCommerce
Elementor/WPBakery page builder
As we said, you need to select a proper image size for all elements that have this problem https://gyazo.com/2403b1e2106a2216dd8d8c98b71ecf1a
Note that the issue is caused by your server configuration. It doesn’t support custom image resizing with PHP. That is why you need to use predefined image sizes only.
