fix the php.ini

[addisoncave]

I've PHP 7.0.8 installed along with Apache 2.4.18 and i've Mysql. I'm hosting with different name(other than Localhost)... i make a virtual host and place my phpMyAdmin there and after that it tell me mbstrig is missing. it's my 5th virtual host and i've made no change in my php.ini but still it make this error before that i was hosting 4 virtual hosts then it didn't give me that problem.
what could be the problem, may i need to do some changes for my 5th virtual host?

Then install mbstring, since it's basically telling you that it's missing. It has nothing to do with your vhosts, it's a requirement for the script or software you're trying to run as the 5th site.

If you're on Debian/Ubuntu, login to SSH and run

sudo apt-get install php-mbstring
