Chrissolve on "After moving to new url,login doesn't appear"

Hi,

I read a lot of articles of how to move a wordpress site from a subdirectory to a main domain. But unfortunately nothing helps. Here's the problem:

I assigned the site form http://www.internet-ideas.de/goodbyewahnsinn to the dominance goodbye-wahnsinn.de . After changing the site home to goodbye-wahnsinn.de, the login attempt results in an empty page. The content can be seen without pictures and all links result in an internal server error.

Before I moved, I replaced all database urls by the new ones by the plugin "search & replace".

I exchanged the old url in the SQL fields wp_options/ sitter and /home to http://goodbye-wahnsinn.de .

I also inserted in the wp-config.php:
define('WP_SITEURL', 'http://goodbye-wahnsinn.de');
define('WP_HOME', 'http://goodbye-wahnsinn.de');

it also doesn't help.

.htaccess is like this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
