Ok, I found the problem – I had redirected wp-activate.php to wp-activate-custom.php in my .htaccess
RewriteRule ^wp-activate.php(.*)$ wp-activate-custom.php$1
as soon as I remove this, it works again. So, while this is not theme issue, you still might be able to help me on this one – maybe you know a way how to make this work? Basically, I did some changes to the activation page, and would like to make the changes update-safe – that’s why I created the custom file..
Any idea?
Sorry about the troubles.
