 * Hello [@filewalker](https://wordpress.org/support/users/filewalker/)
 * Please ensure that the **Free Button plugin is fully deactivated**, as it may
   conflict with the Pro version. After confirming it is inactive, activate the **
   Pro Button plugin** and refresh your website.
 * Please note that the **Free Button plugin and the Pro Button plugin cannot be
   active at the same time**, as both load similar scripts and functions. Activating
   both together may cause conflicts, including installation or functionality issues.
 * This should resolve the issue. If the problem persists after following these 
   steps, please let us know and we’ll be happy to investigate further and assist
   you.
 * Thank You
