I got like white screen on my frontend and my wp-login too after I installed the bruteforce patch. This is the error I see in the error log.
[22-Dec-2014 02:07:53 America/Denver] PHP Fatal error: Cannot redeclare GOTMLS_update_log_file() (previously declared in /home2/paperwir/public_html/lightadreamcom/wp-content/plugins/gotmls/safe-load/wp-login.php:10) in /home2/paperwir/public_html/lightadreamcom/wp-content/plugins/gotmls/safe-load/wp-login.php on line 42
I managed to resolve it after the rename the safe-load directory. I had other login protection plugins installed.
