phpmyAdmin admin page displays only "demo server" - apache

Question

Linux Mint 18
Apache2 server
MYSQL Server
Hello! Does anyone have a moment to advise me?
Here's my problem in brief: I am trying to configure phpMyAdmin on a Linux Mint 18 computer, but when I try to view http://localhost/phpmyadmin/, I get a "phpMyAdmin demo server" screen.
Details:
The phpMyAdmin web page begins with an addJSON statement, and echoes this message:
'You are using the demo server. You can do anything here, but please do not change root, debian-sys-maint and pma users'
I understand I am viewing some sort of demonstration page for phpMyAdmin, but I would rather view the actual, familiar phpMyAdmin administration page.
Do I need to edit the Apache2.conf file? Or something else? Thank you very much for your time.
Eric

I had the same problem, but my error was because I commented the Handler in php.ini
<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>

Answer 4

Perhaps PHP code is not being executed, instead code shows on the page or Apache shows php code instead of executing may help.
Linux Mint is similar to Ubuntu/Debian, so you need the libapache2-mod-php5 package installed (assuming you've used the package manager to install the rest of your PHP/Apache stack): sudo apt-get install php5 libapache2-mod-php5.
You can test this further by adding a file (called test.php or phpinfo.php or whatever else suits you) in the main phpMyAdmin folder with the content <?php phpinfo(); ?> -- then try to load that file directly and see if you get a long list of system status or simply the contents of the file displayed. The main reason to put it in the phpMyAdmin folder is that your Apache configuration might handle different folders differently, this is the simplest way to test what happens on that particular folder.
