phpMyAdmin and “mysqli extension is missing” error
"mysqli extension is missing" error coming from phpMyAdmin means it can't find the php-mysqli module, which is pretty standard. Install apt-get install php5-mysql then, php5-mysql replaced mysqli or integrates the fixes it originally supplied.
After the apt-get install you will still get the error as you need to restart your server after that! Otherwise, in case you run php by default as fcgi the php running is the older one without the mysql / mysqli module.
