@guidedself: If you require assistance then, as per the Forum Welcome, please post your own topic.

Try removing the plugin through the FTP.

Navigate to your WP installation, then wp-content/plugins, and rename the better WP security folder to something else.

Also, according to the sticky thread:

Finally, if you’re locked out of your site due to a server error open your .htaccess and remove the Better WP Security section from it. As much as I try to make this plugin perfect on all sites the fact is it is an impossible tasks. Certain server configurations can indeed cause issues. Fortunately, once we get you back in your site we can then determine which feature is conflicting and solve it.
