The problem you are describing is caused by an older version of the recent new POST Request Attack Protection Bonus Custom Code. We created an automated fix for this problem in BPS Pro 11.4 when you upgrade to BPS Pro 11.4, but you can manually fix this by using FTP or your web host control panel file manager and delete these 2 files: /wp-content/bps-backup/autorestore/root-files/auto_.htaccess and your BPS root htaccess file. Then log into your site and add these 2 new lines highlighted in Yellow below to your POST Request Attack Protection Bonus Custom Code that is saved in BPS Custom Code, click the Save Root Custom Code button and do the rest of the Custom Code steps.
# BPS POST Request Attack Protection
RewriteCond %{REQUEST_METHOD} POST [NC]
# NEVER COMMENT OUT THIS LINE OF CODE BELOW FOR ANY REASON
RewriteCond %{REQUEST_URI} !^.*/wp-admin/ [NC]
# Whitelist the WordPress Theme Customizer
RewriteCond %{HTTP_REFERER} !^.*/wp-admin/customize.php
