[Resolved] Pb with coming soon page

Good Morning GP,
My coming soon page is enabled but after log out wordpress, it doesn’t work and we can access to the web site. It’s a good plugin, I don’t say that only because the builder is French 🙂 I talked about this problem with my hosting, no problem for them. I didn’t put a particular IP adress, I cleaned the memory, I tried to find a solution from the forum, now I try to ask your famous knowledges who has ever helped me not long time ago. An important thing for your diagnostic, like Dr House 🙂 When the coming soon page is enabled, the words “Maintenance enabled” appear on the top, they are winker (they appear, they desappear…)
Thanks for your help, and congratulation if you understand me 🙂
