I was building a WP site on a temporary domain: http://dev6.reklamfirman.com
When I migrated the page to its final domain something broke. Before it went wrong, I installed the plugin "change wp url". I tried this plugin other times and it worked. But not this time, the index page does not work, I can not login on wp-admin and the characters å ä ö doesnt work.
Error respons when logging in to the old domain: You do not have sufficient privileges to access this page.
Error responses when logging on to the new one: Warning: Can not modify header information - headers Already late by (output started at in / var / www / virtual / angensgard.se / http://www.angensgard.se / wp-includes / pluggable.php on line 881
I am using the same database. Have gone in and changed the home url and site url. Via ftp I tired removing all plugins but it did not help either.
You can check the new site here and you will see that the "hem"=home is linked to the developer site: http://www.angensgard.se/butik/
Any tips on how I can fix?
