[SMF 2.0b3p] Changing "Use database driven sessions" gives session error

[TheCoolGamer]

When you in the admin panel go to "Feature configuration" and then change the box after "Use database driven sessions" you get the following error:

Session verification failed. Please try logging out and back in again, and then try again.

The setting is changed though.

This is caused because after this a new session key is generated, which doesn't match the number in the browser.

No mods or something else installed.

I think this bug is related to this one here:

They are related in the way that they both have something to do with the session key. This is a way (there a other ways) to change the session key. Which let the session key check fail.

This is a bug when the session key is wrong error is shown.

Those are two different bugs, However this one can let the one in the link happen.

I appended this information to the bug report. I think they are related in a way. But if not, the developers will be in that same area fixing the bug so they are semi related.

The issue is because when you switch them, the session is not in either the database of flat files. So a new one is made by php (smf doesn't do this).
