Hi

I had tonight update my last version portal to 4.5. I do have received an upgrade error.log (can attachedit if needed) Now I can't no longer login with my username. I upgrad my portal with the upgrade packet and did not overwrite my web.config file.

As this was not working I try to use the release.config file from the upgrade packet and input my machine key section and the database settings.

It do not help. I can't still logged on. Another way to solve the problem was to open the portal for registration and create a new user. Then I copy the password from the new created user into my host account. In the past this was a way to solve problems like lost password or wrong machine key. But.... I receive now the errormessage "Invalid length for a Base-64 char array."

Thank's if anybody has an idea how I can solve my problem.

I have the same problem. So I created a new site with 4.4.1 then did an immediate upgrade to 4.5. After the upgrade I could not login as admin or host.

Thank you for your help. The problem is that I'm not able to change the password of the existing  users. So I can logon with my new created user and then I was trying to reset the password of the old host user I receive the message with the wrong base-64 encoding.
