In case the client needs to switch over to .net and not go with .com. Can you have both domains at the same time? I was looking at the minds.com and minds.org, and it looks identical. I have sent them a private message with no response yet

I'm still not understanding the issue, if they want to go with .net later then just change the config url...

@mario you can change the settings for the URL anytime as Matt was saying. if you choose .net then make the server forward .com to .net and vice versa.

server admins can just change the A record for .com/.net in the DNS zone file.

I don't see that behaviour so it is clearly server specific.

Elgg 1.8.2 is the current release. Have you tried that?

Sounds like your server does not support sessions.

@Cash i think there is problem in his web browser
@check you web cache that your web browser support cache or not
