Error Login

I have presented this error in this Topic and the error has been fixed.

In the next updates, the error fix has not been included in the Plugin, I have to do it manually according to the instructions and everything works fine.
However, about 1 month ago, after updating the Plugin, I followed the instructions but many members responded about the error when logging in: They said they were logging in normally, then did not log out but stopped using it, after a while they logged in and reported that the account was logged out, but when logging in again, the system reported that they were logged in at 2 locations.
