This function was automatically disabled in code starting theme version 3.7.  Help to update the theme – https://help.wpresidence.net/article/how-to-update-the-theme/

There is a function that protects the core plugin and de-activates automatically so that there are no errors from using the plugin with other themes.

The code can be removed via FTP in plugins/wpresidence-core/wpresidence-core.php

Delete the entire “if” function or just the lines with deactivate and wp_die
