Plugin has disappeared of my blog

Hello!

I’m a french WordPress user and I use WP Socializer.

There is a strange problem with this plugin since few days/weeks : it doesn’t work at all ! I don’t remember since which day the plugin has disappeared.

I desactivated all plugins but nothing, the plugin doesn’t appear on my blog (but it is present in the source code). I use follow bar and text sharebar !

My website : https://blog.pierrepineau.fr/

Thank you for your help !
