Probably requires both a wp-admin skip/bypass rule and a root skip/bypass rule:
1. Copy this wp-admin skip/bypass rule to this BPS wp-admin Custom Code text box: CUSTOM CODE WPADMIN PLUGIN/FILE SKIP RULES
# post.php skip/bypass rule RewriteCond %{REQUEST_URI} (post\.php) [NC] RewriteRule . - [S=2]
2. click the Save wp-admin Custom Code button.
3. Copy this root skip/bypass rule to this BPS Root Custom Code text box: CUSTOM CODE PLUGIN/THEME SKIP/BYPASS RULES
# Plugin Name Here skip/bypass RewriteCond %{REQUEST_URI} ^/wp-content/plugins/js_composer/ [NC] RewriteRule . - [S=13]
4. click the Save Root Custom Code button.
5. Go to the Security Modes page, click the Create secure.htaccess File AutoMagic button, Activate Root Folder BulletProof Mode and Activate wp-admin BulletProof Mode.
