[SOLVED] logging in to umbraco 6.1 backend doesn't work anymore, keep getting errors and redirect back to login.aspx page

logging in to umbraco 6.1 backend doesn't work anymore, keep getting errors and redirect back to login.aspx page

after nog using the backend of our umbraco website for a few months I started developing for our website again. As the website was being used by some people, I decided to use a staging environment. So I moved all my files and finally got the database also cloned.

But now whenever I try to login to the backend of umbraco (in the live and the staging environment) I get a javascript error in my firebug console:

{"Message":"The user has no umbraco contextid - try logging in","StackTrace":"   at Umbraco.Web.Security.WebSecurity.ValidateCurrentUser(HttpContextBase httpContext, Boolean throwExceptions)\r\n   at Umbraco.Web.Security.WebSecurity.AuthorizeRequest(HttpContextBase httpContext, Boolean throwExceptions)\r\n   at Umbraco.Web.WebServices.UmbracoAuthorizedWebService.AuthorizeRequest(Boolean throwExceptions)\r\n   at Umbraco.Web.WebServices.UmbracoAuthorizedWebService.AuthorizeRequest(String app, Boolean throwExceptions)\r\n   at umbraco.presentation.webservices.TreeClientService.GetInitAppTreeData(String app, String treeType, Boolean showContextMenu, Boolean isDialog, TreeDialogModes dialogMode, String functionToCall, String nodeKey)","ExceptionType":"System.InvalidOperationException"}

As suggested in other posts, I delete my cookies and try again, but no luck.

I also get some other errors from time to time:

uiKeys is undefined

I uploaded my umbraco/config/lang folder using Binary, but I still get the error sometimes

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

I added this to my web.config

<pages enableEventValidation="false" validateRequest="false" viewStateEncryptionMode ="Never" />

and the error seems gone

I also got some error about synthax in the document type declaration at the start of the logout page which I get redirected to

I have been at this for several hours and can't seem to fix it.

Locally loggin in works.

Edit

I just did a fresh install of 6.1.6 and 6.1.5 and tried to logon but I still get the error: http://staging.mydomaimn.com/umbraco/webservices/TreeClientService.asmx/GetInitAppTreeData 500 Internal server error: {"Message":"The user has no umbraco contextid - try logging in","StackTrace":" at Umbraco.Web.Security.WebSecurity.ValidateCurrentUser(HttpContextBase httpContext, Boolean throwExceptions)\r\n at Umbraco.Web.Security.WebSecurity.AuthorizeRequest(HttpContextBase httpContext, Boolean throwExceptions)\r\n at Umbraco.Web.WebServices.UmbracoAuthorizedWebService.AuthorizeRequest(Boolean throwExceptions)\r\n at Umbraco.Web.WebServices.UmbracoAuthorizedWebService.AuthorizeRequest(String app, Boolean throwExceptions)\r\n at umbraco.presentation.webservices.TreeClientService.GetInitAppTreeData(String app, String treeType, Boolean showContextMenu, Boolean isDialog, TreeDialogModes dialogMode, String functionToCall, String nodeKey)","ExceptionType":"System.InvalidOperationException"}

This is on a fresh install that never had logins before Perhaps the problem is with the database setup. My host uses MSSQL 2012 and I have two databases, the first is for the live version which is called 'myloginname' and the second is for the staging which is called 'myloginname_1'. is the _1 a problem when placing the logon in the database (which I read Umbraco does)?

Edit 2

just looked in my database and Umbraco does create a contextId in the db table 'umbracoUserLogins' but does not create the cookie which should contain the same 'UMB_UCONTEXT'

so this is probably my real problem, what could be causing this?

Edit: some more info on this: When I look in Fiddler I can see this: On the 'Raw' tab:

HTTP/1.1 302 Found Cache-Control: private Content-Type: text/html; charset=utf-8 Location: /umbraco/ Set-Cookie: ASP.NET_SessionId=zjlqfoxq421wmnpeydcbxv1t; path=/; HttpOnly Set-Cookie: ASP.NET_SessionId=zjlqfoxq421wmnpeydcbxv1t; path=/; HttpOnly Set-Cookie: UMB_UCONTEXT=694C3[...a lot of text...]CFDD5EDB; expires=Tue, 12-Nov-2013 14:07:23 GMT; path=/; HttpOnly Date: Mon, 11 Nov 2013 14:07:23 GMT Content-Length: 126

The cookie tab shows:

Response sent 1318 bytes of Cookie data: Set-Cookie: UMB_UCONTEXT=694C3[...a lot of text...]D5EDB; expires=Tue, 12-Nov-2013 14:07:23 GMT; path=/; HttpOnly This response did not contain a P3P Header.

So we can conclude:

the expiration time and date are correct
there is a 302 error, but this seems to be for all cookies and the other two mentioned are created (I'm confused about this)
perhaps the P3P headers are an issue?

Solution

I was able to fix this. The reason why the UMB_UCONTEXT cookie wasn't created was that I fixed the error

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

the wrong way. As How To Fix the: “Validation of viewstate MAC failed” Error (ASP.NET MVC) shows, I needed to create a random machinekey and add it to my web.config
