Carta, including both theme and plugin, has no Support guarantee and is provided as is. Updates for fixes and new features will be released when necessary and messages will be answered at the best possible rate, but it cannot be guaranteed. In no case customizations will be provided for specific users.
The free, theme part of Carta, can be used in any number of commercial and personal WordPress websites.
The plugin part of Carta, Carta Maker, once purchased can only be used in a single WordPress website. Therefore, separate purchases should be made for each online WordPress website.
Currently, the Plugins that are supported by Carta are the ones integrated in its functions. They are:
- Jetpack by WordPress.com. Carta supports its Portfolio and Testimonials features and makes extra adjustments for the included Contact Form and Widgets.
- WooCommerce. Carta supports all its Products features and goes beyond by replacing its styling and including extra features intertwined with its functions.
- WP Smush. Carta supports WP Smush by using its compression to for the images it creates.
The remaining, vast majority of well-crafted Plugins will very likely work seamlessly as well, but it can't be guaranteed.
