I am receiving the below message. I have reviewed the settings, everything appears to be working. The plugin appears to be working but of course seeing an error don’t think I am outside the update period.

How may I go about fixing this glitch and prevent it from happening again?

A license key for stripepaymentgateway could not be found. Maybe you forgot to enter a license key when setting up stripepaymentgateway, or the key was deactivated in your account. You can reactivate license key at your plugin settings page.
