Fatal Error and can not login after deactivating

Hello,

I cleared the wp rocket cache of my site only.

I got the following fatal error now:

Fatal error: Uncaught LogicException: Function ‘AAM_Autoloader::load’ not found (class ‘AAM_Autoloader’ not found) in /html/wordpress/wp-content/plugins/advanced-access-manager/autoloader.php:74 Stack trace: #0 /html/wordpress/wp-content/plugins/advanced-access-manager/autoloader.php(74): spl_autoload_register(‘AAM_Autoloader:…’) #1 /html/wordpress/wp-content/plugins/advanced-access-manager/aam.php(236): AAM_Autoloader::register() #2 /html/wordpress/wp-settings.php(305): include_once(‘/html/wordpress…’) #3 /html/wordpress/wp-config.php(117): require_once(‘/html/wordpress…’) #4 /html/wordpress/wp-load.php(37): require_once(‘/html/wordpress…’) #5 /html/wordpress/wp-admin/admin.php(31): require_once(‘/html/wordpress…’) #6 /html/wordpress/wp-admin/index.php(10): require_once(‘/html/wordpress…’) #7 {main} thrown in /html/wordpress/wp-content/plugins/advanced-access-manager/autoloader.php on line 74

When I rename the folder on ftp server the Error is gone but I cannot login to my site (name filed is empty…).

Would be great if you can help me.
