Error with "last post" and "last visit" dates.

[pequeno]

In many of my users, the date of the last visit is prior to the date of the last post.

For example:
Last post :  10/11/16     Last visit: 26/09/16

Nothing about? Can someone help me?

Exactly.

The last visit date won't be updated if they logged in anonymously
