Ok – so i see you’re hosting is with WordPress.com – do you have a Business Account with them ? As this would be required to install plugins like GeneratePress Premium
J’AI BIEN RENVOYER HIER SOIR L’ACCORD ADMINISTRATEUR MAIS L’ADRESSE EMAIL ETAIT NECESSAIRE ET JAI DONC PAS LA VOTRE DONC J’AI ENVOYER LES LIENS. J’AI MIS UNE DE MES ADRESSE EMAIL, JE NE SAIT SI CELA FONCTIONNERA.
If you’re using WordPress . com then yes they charge you to add plugins (extensions) to the site.
It is not within our control.
We recommend people use a Hosting provider that offers managed wordpress solutions. They are usually less expensive and provide better flexibility.
