This error typically indicates the file you are trying to upload is not an Elementor template kit that is compatible with the Envato Elements / Template Kit Import plugin.
Our plugin supports items found under the Template Kits > Elementor category on Envato Market only https://themeforest.net/category/template-kits/elementor
On Envato Elements, these items are under WordPress > Template Kits, however the Envato Elements plugin already displays this library for direct import if you have a subscription. https://elements.envato.com/wordpress/template-kits
If you have a subscription, be sure to connect your subscription, then import the kit directly from the Elements > Template Kits are of your WordPress admin. See How to Use the Envato Elements plugin for a full guide
If you purchased your item on Envato Market, make sure the item title says "Elementor Template Kit".
- If your item says WordPress theme, please see How to Install a WordPress Theme from Themeforest
- If your item says Site Template, HTML Template, XD Template or any other template type, it is probably not compatible with WordPress and cannot be installed using our plugin.
Tips for installing Elementor Template Kits:
- Download your file again and ensure it is not being unzipped. If you have Safari browser, you must ensure "Open Safe Files After Download" is disabled under Preferences.
- Upload the kit zip file to Elements > Installed kits (Elements plugin) or Tools > Template Kits (Import plugin)
