Can't change WP-Dir

Hello!

Need a solution for this situation:
– I have activated the rename of wp-login in the shield login-protection to AAA
– I have renamed the WP-installation directory
– got a white screen on URL/AAA
– **reset to old values, logged in**
– Set wp-login-rename to ” (Empty)
– rename WP-inst-dir
– successfully logged in via URL/renamed-wp-inst-dir/wp-login.php
– set the wp-login-title via shield-login-protection again to AAA
– result: getting again a white screen on URL/AAA

Hope anybody can help,

Thanks, so far,
