WordPress Security update

Hello there,
Every time Real Simple gets an update, WordPress will no longer work and my page becomes unavailable and unsafe.
After receiving this email info: (These plugins are now up to date:
– Really Simple SSL (from version 4.0.15 to 5.0.2)).

My site wont open until I chat with you WordPress. The issue is that my page becomes UNSAFE and really Simple SSL will no longer work.

Can someone help me correct this issue once for all?
Thank you
Luiz
