Manager session not recognized when url is changed to/from www

The fix I mentioned to the config.inc.php file would make the same cookie work for www.domain.com and domain.com, but the rewrite method is probably better. If it’s working now for your manager, I wouldn’t worry about it.

You do have the ht.access file in your /manager/ folder renamed to .htaccess, with just one line in it?

No, I did not rename that file and it’s still in there as ht.access. Is that a problem?

I guess not, if your manager is working. Generally though you don’t want your manager pages to be re-written as you do front-end pages, so I suppose under some conditions it might make trouble if a module does something odd with the urls. The rewrite rules are looking for index.php?q=..., while the manager pages are index.php?a=... so I suspect the turning off of the rewrite engine is more for a performance benefit than anything else. But if you need to have the www thing dealt with, then it’s useful to be able to leave it working in manager too.
