Problems after transferring to new server

[eluser]weboap[/eluser]
try this .htaccess

Code:

Options +FollowSymLinks
RewriteEngine On
RewriteBase /

RewriteRule ^$ index.php [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond $1 !^(index\.php|robots\.txt|favicon\.ico)

RewriteRule ^(.*)$ index.php?/$1 [L]

also check your sessions / server time

and post some code from the controller that you are initializing.
