After the update, you will be logged out immediately after logging in

Hi,

Sorry to hear that.

This could be caused by a new Shield’s v19.0 “User Session Lock” feature.

But to be sure, this is what we recommend:

1. Reproduce logging out
2. Use a forceoff method outlined here
3. Log into your site
4. Go to your Activity Log and filter logs by your IP address or username.
5. Review logs. Hopefully, these will tell you why you’re logging out so you can change Shield settings to prevent it from happening again.

Let us know how you get on.
