[solved]Backoffice false url in production

[Inform-All]

So when i go to the backoffice i get redirected to  'domain.com/domain.com/admin1233'.
And in debug mode, it works fine!

I already regenerated the htaccess files, and also manually cleared cache (in var/cache/prod & dev) and regenerated class_index.php.
The server is not using Nginx, so that should not be the issue either. I even tried with ssl disabled, but nope.  The apache logs don't tell me anything either, so any ideas would be really welcome

Prestashop 1.7.4.4
PHP 7.1

Weird, it seems that i have the same bug/error happening in a second shop. And both are on different hosting.

Found the problem!
For other people facing the problem: Check if there is odd folder in /var/cache/prod if so delete it and afterwards delte class_index.php in the same folder.

aka... basic cache problems 😓
