I just upgraded from 1.9.1 to 2.1.0 and cannot login with old member.

I am getting "The username or password is incorrect. Please try again".

When I register new member I see entry in DB but login also does not work.

From Event Log I see:

Event code: 4005

Event message: Forms authentication failed for the request. Reason: The ticket supplied was invalid.

Any idea how to recover login for old members and what to do for new ones?

Thanks,

Following is the error message I got from event log.

Well one reason for the login problem could be, that on upgrade you override the web.config and the machine key is different from the previous version.

I checked old web.config and there I did not have machine key.

Also in new web.config I do not use machine key.

From commented lines I see that machine key should be used in case:

and I do not have this type of scenario.

Any other suggestion?

Thanks in advance

Failure Initializing User/Page. System.ApplicationException: Unable to find the Guest User! at YAF.Core.LoadPageFromDatabase.Handle(InitPageLoadEvent event)

Btw. new users are created in table yaf_prov_Membership and not any more in yaf_Users.

Of course, as old users are in yaf_Users table I cannot login any more with any of old users.

Is there any way to switch back to yaf_Users table?

Thanks
