We are interested in purchasing the Login Lockdown & Protection Plugin from https://appsumo.com/products/wp-login-lockdown/. This plugin is a WordPress plugin with a three-code plan that includes all the features mentioned above.

1). Unlimited websites

2). Centralized dashboard for controlling sites, licenses & IP access lists

3). White-labeling

4). Rebranding (no code editing needed)

Can someone tell me after installing and why is a Fatal error: Uncaught Error: Call to

function ImageFontWidth() in /home/lotshub/public_html/wp-content/plugins/login-lockdown/libs/functions.php:653 Stack trace: #0 /home/lotshub/public_html/wp-content/plugins/login-lockdown/libs/admin.php(40):

Thank you
Edmund Tan
