Had an issue with mysql on the server so decided to completely remove it via the following
sudo apt-get remove --purge mysql-server mysql-client mysql-common
rm -rf /var/lib/mysql
rm -rf /etc/mysql*
then the following to reinstall
apt-get install mysql-server mysql-client
After adding my the relevant DBs, tables & content I would have thought the websites would have resumed as normal. As it stands the page doesn't load but doesn't give any error message which made me think it might be messing with apache in some fashion.
But checking the apache error log doesn't show any errors, any ideas?
UPDATE
It appears i need to reinstall mysqli, just need to remember how I done it last time.
