Wordfence problem on login

Hi
I have uploaded my site to PHP 5.4 but WordPress give me “Error page” on login.
This is the error “Il sito sta avendo problemi tecnici. Controlla la casella di posta dell’amministratore del sito per istruzioni.”
The only solution is rename the Wordfence’s Folder on FTP and the login page will be available again.
I tried to upload Wordfence too but the login page does not work again.
The issue is only on backend, on frontend the site working regularly with Wordfence.

The wordpress version is 5.2

Solutions?
