Error after login

Hi,

since version 5.7.8 after a user login there is this error: “Sorry your nonce has not verified”

My last working version is 5.7.7 and I can’t update because otherwise I find the problem.

I tried to update all the later versions up to 5.8.1 but I always find the error after login and I am forced to downgrade the plugin to version 5.7.7. (the only one working)

Thanks
