Sofquipeut on "[Plugin: All in One SEO Pack] Join our mailing list message"

Hello,
I had to upgrade the plugin today.
The problem is when I get to the general settings, I get the message :

"All in One SEO Pack Plugin Options
Rejoignez notre mailing liste pour recevoir des trucs, astuces et secrets sur WordPress.

Inscrivez-vous aujourd'hui et recevez un exemplaire gratuit de l’e-book 5 SEO Tips for WordPress (d’une valeur de 39$)."

I subscribed but still, I cannot access the general features...
Same thing on performance, feature manager and social meta pages...

Can you help ?
Thank you

What features can you not access? Subscribing to the mailing list is not a requirement to access any features. It's nothing other than a subscription form.

I cannot access anything actually.
I always get this message : join our mailing list ...

Please post a screenshot with the problem you're seeing.

That's strange. There may be a conflict with another plugin or theme.
Try the steps listed here: https://semperplugins.com/documentation/how-to-troubleshoot-issues-with-all-in-one-seo-pack/

Start with deactivating all other plugins and your theme to see if the problem goes away.

Once we've narrowed down what the problem is, we'll determine how to fix it.

I have tried everything : deactivating all other plugins, change the theme to Twenty Sixteen... but still, I have this page...
It seems like the plugin works ok though but I cannot change the settings...
FYI, I am using Customizr Pro theme and the latest version of WordPress 4.5.3 .
