Interesting. I have never heard of MariaDB before. “MariaDB is a drop-in replacement for MySQL.”
WordPress Requirements: http://codex.wordpress.org/Hosting_WordPress#Server_requirements
Server requirements
- WordPress server requirements for Version 3.2+:
- PHP version 5.2.4 or greater
- MySQL version 5.0.15 or greater
- (Optional) (Required for Multisite) Apache mod_rewrite module (for clean URIs known asPermalinks)
MariaDB compatibility with WordPress: https://mariadb.com/blog/how-install-and-run-wordpress-mariadb
It appears that MariaDB is compatible with WordPress, but since MariaDB is not listed in the WordPress Server requirements we would not test MariaDB. BPS has been tested on XAMPP, MAMP, LAMP and WAMP and works normally.
Check your database and do a general search for all of the bulletproof_security database options in the WordPress xx_options database table: LIKE %bulletproof_security% to ensure that all BPS database options are actually being saved correctly. Then check this specific database option: bulletproof_security_options_net_correction. You should see these values:
a:2:{s:17:"bps_net_automagic";s:9:"automagic";s:17:"bps_net_activated";s:9:"activated";}
