What happens when the license expires?

Once the license expires, you will still have complete access to the theme. However, you will no longer be able to receive updates or support until the license is renewed.

If you purchase a premium theme and reach the end of your support period without renewing your license, do you have to stop using the theme?

No, your theme itself will be unaffected. You can continue to use it as-is for as long as you like. However, you will stop receiving updates and support from the developer until you reactivate your license.

From a legal perspective, this is perfectly fine. The GPL guarantees that you can keep using the theme indefinitely. However, from a technical perspective, you may run the risk of future bugs, conflicts with plugins or WordPress updates, and security vulnerabilities.

I have another question

No problem! Feel free to contact us if you have any other questions about the theme upgrade.
