crash of website when trying to Manage a User

Hi Joe,

From the memberlist I try to access the ManagerUser page. The Server error below appears.

I am using MS SQL 2005 and Mojo 2246

Re: crash of website when trying to Manage a User

Hi Roger,

Sounds like its trying to decrypt a password that isn't encrypted or possibly one that was encrypted with a different machine key. I would look in the db and see if it looks like an encrypted password or not.

Is this happening on just one user or on all users?

When you upgraded you got the new web.config file. If your old Web.config file had a custom machinekey then you need to restore it from your old web.config. If the machine key changes it can't decrypt anything that was encrypted with the old key so its important never to change your machine key.

There is a known bug when you create a new site it fails to encrypt the new site admin's password, so you should create the site with plain text password format and then after its created you can change it to encrypted and will encrypt it correctly that way. This bug isalready fixed in svn.

Hope it helps,

Joe

Re: crash of website when trying to Manage a User

Hi Joe,

Sorry for my late reply.

I have tested your suggestions.

The machine keys in both the old web.config and the new.config are the same.

It happens to all users.

Also the following (I suspect it has something to do with my problem) server error occurs when trying to recover a password:

Server Error in '/' Application.
--------------------------------------------------------------------------------

Length of the data to decrypt is invalid.

Thanks,

Roger

Re: crash of website when trying to Manage a User

Hi Roger,

I dug into this further today and believe I have found and fixed the cause of the problem. I will be uploading a new set of release packages in just a little while.

Thanks,

Joe
