Migrating from one server to another

I moved my installing from one server to another.  Both Windows Server 2008 R2.  Got SQL migrated over.  The sites are working fine... or so I thought.  The second I go to /admin to login, I get the error "object reference not set to an instance of an object".  There are no specifics so I'm stuck.....I can't login to any of my sites at this point.

Re: Migrating from one server to another

make sure the server is fully patched with all windows updates, missing updates can cause problems with IE 11 or 10 and logging in.

check the windows application log to get more detail about the error if you post the error details then maybe we could help but without it not so much

when posting about errors indicate whether you mean a server side error or a javascript error in the web browser, I don't know which you mean in this case

Also I would double check the file system permissions sometimes funky permissions occur because the file system objects are owned by a user sid that doesn't exist on the new machine. The /Data and /App_Data folders and all their child objects must be under full read/write control of the user that is the identity on the app pool.

A variety of errors can happen if file system permissions are messed up.

Re: Migrating from one server to another

I ran setup again to make sure all permissions read/write were setup properly and they are.

Re: Migrating from one server to another

Ok, so the error says that something is null in the PopulateControls method of the login control. Looking at the source code for mojoPortal.Web.UI.LoginControl.cs, you can see what that method does and it is getting references to controls that should and do exist in the corresponding LoginControl.ascx file. But in your case it seems that something expected is missing in your copy of the LoginControl.ascx file so its getting null on something that should not be null.

Perhaps you've modified the code yourself or perhaps the file was corrupted somehow during migration and needs to be re-copied.

Hope that helps,

Joe

Re: Migrating from one server to another

"I ran setup again to make sure all permissions read/write were setup properly and they are"

Our setup page does not detect all file system permissions problems and it does not correct any file system permission problems.

Re: Migrating from one server to another

You must have been right something happened in the file transfer.  I upgraded to the latest version of mojoportal and all is good now!  

 

Thanks for your help on a Sunday!  Have a great day!
