We have found that security and maintenance mode plugins such as Solid Security or WP Maintenance Mode have security features that interfere with license key API requests. These could be the reason you aren’t able to activate your license.
There are a couple of options to resolve this conflict:
- Temporarily disable the security plugin.
- Attempt to activate your license.
- If it still won’t activate, log in to the member portal and open Downloads. If the license shows all its activations used, deactivate a site you no longer use and try again.
- If that doesn’t help, contact us from the Support tab in the member portal.
There are some options within security plugins that you can disable which may help avoid blocking the API request (see the article below). With maintenance mode plugins, the best solution is to temporarily disable them in the WordPress “Plugins” screen in order to activate S3 Media Maestro.
