Cannot login to WP dashboard after installing iThemes Security

Cannot login to WP dashboard and URL address does not show website – get “error” on a blank screen.

Just downloaded the iThemes Security Plugin for a client and we added BRUTE FORCE and VIRUS TOTAL.

We changed the password on the client’s account and now we cannot get into the client’s account –

We received an email from iThemes saying they locked us out of the account.

Need serious assistance to solve this problem. Email us at mtshastadesign@gmail.com

Thanks
