Sorry for the inconvenience. This usually happens when the site cannot properly communicate with our activation servers, or when the activation status is cached.
Please try the following steps first:
Go to LayerSlider → Plugin Settings → System Status and check if there are any warnings related to server connectivity, cURL, SSL, or blocked requests.
Make sure your server/firewall/security plugin is not blocking outgoing connections to LayerSlider’s servers.
Clear all caches, including any WordPress cache plugin, server-side cache, CDN/Cloudflare cache, and browser cache.
Activating plugin is not registering with you, so I still receive the message attached.
