[Plugin: BulletProof Security] 403 Forbidden Error

my .htaccess on root:

#   BULLETPROOF .47.3 >>>>>>> SECURE .HTACCESS     

# If you edit the  BULLETPROOF .47.3 >>>>>>> SECURE .HTACCESS text above
# you will see error messages on the BPS Security Status page
# BPS is reading the version number in the htaccess file to validate checks
# If you would like to change what is displayed above you
# will need to edit the BPS /includes/functions.php file to match your changes
# If you update your WordPress Permalinks the code between BEGIN WordPress and
# END WordPress is replaced by WP htaccess code.
# This removes all of the BPS security code and replaces it with just the default WP htaccess code
# To restore this file use BPS Restore or activate BulletProof Mode for your Root folder again.

# BEGIN WordPress
# IMPORTANT!!! DO NOT DELETE!!! - BEGIN WordPress above or END WordPress - text in this file
# They are reference points for WP, BPS and other plugins to write to this htaccess file.

# BPS PRO ERROR LOGGING AND TRACKING - Available in BPS Pro only
# BPS Pro has premade 403 Forbidden, 400 Bad Request and 404 Not Found files that are used
# to track and log 403, 400 and 404 errors that occur on your website. When a hacker attempts to
# hack your website the hackers IP address, Host name, Request Method, Referering link, the file name or
# requested resource, the user agent of the hacker and the query string used in the hack attempt are logged.
# BPS Pro Log files are added to the P-Security All Purpose File Manager to view them.
# All BPS Pro log files are htaccess protected so that only you can view them.
# The 400.php, 403.php and 404.php files are located in /wp-content/plugins/bulletproof-security/
# The 400 and 403 Error logging files are already set up and will automatically start logging errors
# after you install BPS Pro and have activated BulletProof Mode for your Root folder.
# If you would like to log 404 errors you will need to copy the logging code in the BPS Pro 404.php file
# to your Theme's 404.php template file. Simple instructions are included in the BPS Pro 404.php file.
# You can open the BPS Pro 404.php file using the WP Plugins Editor or by using the BPS Pro File Manager.
# NOTE: By default WordPress automatically looks in your Theme's folder for a 404.php template file.
