License Key Activation Issues
So you’ve installed GP Premium, and now you’re trying to activate your license so you can receive automatic updates.
You add your license key to the field, and click the “Update” button, but your license key doesn’t activate.
If you don’t get a specific error, this can happen when your hosting isn’t allowing external communication with other web servers.
To fix this issue, please contact your host and ask them to allow your WordPress installation to communicate with https://generatepress.com using the wp_remote_post function.
They may have to turn PHP cURL on.
Mon hébergeur a fait le nécessaire.
Mais l’activation ne fonctionne toujours pas.
Que faut-il faire ?
