# Symptom

You're using a MapifyPro map on your page/site and you noticed that some of its features had stopped working or some of your changes in the WP-admin are not reflected in the front-end.

# Explanation

It is most likely that you're running on the old version of MapifyPro. While you're licensed to use MapifyPro version 2.x indefinitely, support for version 2.x has ended.

# Resolution

If you purchase the latest version of MapifyPro (version 3.x), you can easily upgrade from the old version. To update to the latest version of MapifyPro, please follow this [guide](https://mapifypro.zendesk.com/knowledge/articles/360055917271/en-us?brand_id=1348006).
