An outdated PHP Version may prevent your PopupAlly plugin from working properly.
To upgrade the PHP version, you need to contact the server support that hosts your WordPress install.
Because this process is unique to each server, please contact your own server support to guide you through this task.
For example: Bluehost users
Instructions for upgrading your PHP version on Bluehost are available on their site: https://my.bluehost.com/cgi/help/447
