I keep getting a message in my WordPress dashboard that a plug-in I use (and want to keep) will no longer support the php version I am using. It says that I should update my site to use PHP 7 or 5.6. To update the php version I am using do I just need to use a more recent theme? If so, where can I find the php version on the theme to make sure it is using the version I need.
Thanks,
Travis
