Client is running WordPress on a very, very old Linux OS (Cent OS 6) and WordPress is complaining that mysqli extension for PHP is missing.
I tried to add it via yum but it is missing in the rpm. I absolutely do not find any location from where to get the neceassry repo files – anyone have an idea how to get mysqli extension installed anyway (and yes, they are in the process of upgrading an up to date Linux VPS, of course).
Modified /etc/yum.repos.d/remi.repo, added several repo urls, no success.
