Please try to modify `wp-config. php` , find these lines: * ``` /** MySQL hostname */ define('DB_HOST', 'localhost'); ``` * and replace `define('DB_HOST', 'localhost');` with `define('DB_HOST', '127.0.0.1');` * Save the change then run the job again.

He asks me to try to downgrade php version, is this a good idea? He told me that this database function ( mysqli:: real_connect() )seems to be functional but he told me that : * “Otherwise this call function of the database must have the data of the base which must be informed, it would be necessary to be able to control the exactitude of its information.” * And then, he asks me to contact plugin support 🙂 * Thank you * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [7 years, 2 months ago](https://wordpress.org/support/topic/error-database-10/#post-11276409) * Hi [@maximeba](https://wordpress.org/support/users/maximeba/) Sorry about the delayed response, could you please try disabled: **pdo_mysql** and **mysqli** and enabled: **nd_pdo_mysql** and **nd_mysqli** in cPanel PHP module Options? * If you can’t do that, try to downgrade php version to see if it works * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [7 years, 2 months ago](https://wordpress.org/support/topic/error-database-10/#post-11303874) * [@maximeba](https://wordpress.org/support/users/maximeba/) * since we haven’t heard back from you, I’m going to mark it as resolved.
