Title: Cannot retrieve WP database credentials Last modified: August 22, 2016 --- # Cannot retrieve WP database credentials * Resolved [Michael](https://wordpress.org/support/users/mkalina/) * (@mkalina) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/) * I recently upgraded NinjaFirewall to * ``` Firewall Enabled PHP hook Enabled PHP SAPI CGI-FCGI Engine version 1.2.6 Rules version 20140810 ``` * Yet I keep getting this error message: * > NinjaFirewall fatal error : cannot retrieve WordPress database credentials. > Please review your installation. Your site is not protected. * How can I help to debug this? * [https://wordpress.org/plugins/ninjafirewall/](https://wordpress.org/plugins/ninjafirewall/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247350) * Hi, * This usually means you made changes to the wp-config.php (DB_NAME, DB_USER, DB_PASSWORD, DB_HOST or $table_prefix) and the firewall cannot parse it. * You can debug it with [this PHP script](http://nintechnet.com/ninjadbcheck_php.txt) and paste the results here. * Thread Starter [Michael](https://wordpress.org/support/users/mkalina/) * (@mkalina) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247355) * Hi, * Thank you for the fast feedback. The result from the script is * ``` cannot read DB_NAME cannot read DB_USER cannot read DB_PASSWORD cannot read DB_HOST cannot read table_prefix ``` * which is odd, as I have not changed anything except adding these lines right in front of “That’s all, stop editing! Happy blogging.”: * ``` define( 'SD_HIDE_MARKDOWN_BOX', true ); define('FORCE_SSL_ADMIN', true); define('DISALLOW_FILE_EDIT', true); ``` * What is the next step for debugging/finding the error? * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247357) * Is the $table_prefix value using single quotes (‘) and not double-quotes(“) ? * $table_prefix = ‘whatever’; < will be okay $table_prefix = “whatever”; < will not be okay * Thread Starter [Michael](https://wordpress.org/support/users/mkalina/) * (@mkalina) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247358) * All values are in single quotes. * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247360) * Can you mask the DB name, username and password and send me a copy of your wp- config.php to contact-at-nintechnet.com ? * Thread Starter [Michael](https://wordpress.org/support/users/mkalina/) * (@mkalina) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247371) * Done. * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247390) * I did not receive it yet. * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247431) * I received it. But if I run the test script, it works: * ``` DB_NAME: OK DB_USER: OK DB_PASSWORD: OK DB_HOST: OK table_prefix: OK ``` * Do you have an encoding issue with the original file? I can see, for instance, it is using CR/LF (Windows format) rather than LF. * Thread Starter [Michael](https://wordpress.org/support/users/mkalina/) * (@mkalina) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247565) * Hi, here is an update. On a completely different server, I have exactly the same problem except that when running your debug-script, everything is okay. Also, there is no additional variables configured in wp-config.php. * This time, however, it is WordPress 4.0 and 1.2.6/20140810. * Plugin Author [nintechnet](https://wordpress.org/support/users/nintechnet/) * (@nintechnet) * [11 years, 9 months ago](https://wordpress.org/support/topic/cannot-retrieve-wp-database-credentials/#post-5247566) * Hi, * I just cannot find out what the problem is. Do you have a wp-config file that works with NinjaFirewall ? You could try to copy it to the server where you have the problem, and simply edit the DB_NAME, DB_USER, DB_PASSWORD, DB_HOST and $ table_prefix, then check if that works ? I am thinking about a possible encoding issue. Or maybe ensure that you uploaded it via FTP using ASCII mode rather than binary ?
