Ubuntu 14.04 Server: Apache2 issue with phpMyAdmin

Question

I have installed Apache 2, and it is working fine. I have installed PHP 7, and everything works fine, But when I install phpMyAdmin, Apache 2 stops working. When checking Apache 2, it even does not load the default page.

When I restart Apache 2, the following error comes up:

root@ip-172-31-30-202:~# service apache2 restart
* Restarting web server apache2                                                                                                                                   [fail]
* The apache2 configtest failed.
Output of config test was:
Segmentation fault (core dumped)
Action 'configtest' failed.
The Apache error log may have more information.

The error log has:

I am using Ubuntu 14.04 (Trusty Tahr).

Answer 1

This worked for me:

cd /etc/apache2/mods-enabled
rm php5.conf 
rm php5.load 

sudo service apache2 start;

It worked :)))))
