Now sorted,enabled mbstring in php

Looks like your php installation missing mbstring functions, if you use a self compiled installation append

--enable-mbstring

to the options.

If you are using php7.0 from stock install the

php7.0-mbstring

packadge.

For php 5.x you need to install

libapache2-mod-php5

after that restart php or php-fpm, nginx does not need a restart apache does.
