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 can see, there is not enough max upload file size limit on your server. In this case, you can try to upload the theme using your hosting control panel. Or you need to contact your server provider and ask to increase this parameter.
