[crit] Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP. Pre-configuration failed Action 'configtest' failed.

how can i fix this problem

Answer 1

Disabling mpm_event and enabling mpm_prefork worked for me.

sudo a2dismod mpm_event
sudo a2enmod mpm_prefork

Answer 2

apache2ctl configtest

sudo apt-get install php7.0
sudo apt-get install php7.0-fpm
sudo a2enmod php7.0
sudo a2dismod mpm_event
sudo a2enmod mpm_prefork
sudo service apache2 restart

Answer 3

The PHP manual does not recommend this

You can run a fast-CGI version of PHP though:

apt-get install php5-fpm should install it for you.
