The apache2 "It works!" page appeared when I used a web browser to go to

http://localhost/

But when I browsed

http://localhost/phpmyadmin

the phpMyAdmin icon appeared in the browser title bar and the message "The mbstring extension is missing." appeared in the canvas. I tried

http://localhost/phpmyadmin/index.php

and got the same thing. However, php7.1-mbstring is installed!

In Nautilus, I browsed to /var/www/html, that is, DocRoot, but there is no phpmyadmin/ folder there! Shouldn't there be a phpmyadmin/index.php file in the doc root (web root?)?

How come I am even getting a message from phpMyAdmin in the browser? And how do I fix the mbstring issue?

  The /etc/apache2/conf-enabled/phpmyadmin.conf file sets up a redirect to /usr/share/phpmyadmin when you access http://localhost/phpmyadmin. But I still don't know how to fix the error message about php-mbstring missing when it is actually present.

  My question about the location of the phpMyAdmin is a duplicate of link, although the answers to that question suggest creating a symbolic link at DocRoot to /usr/share/phpmyadmin.

  How did you install phpmyadmin, this will determine where your phpmyadmin/index.php is. But I suspect you installed it usingsudo apt install phpmyadmin so it should be in that link in your comment. For the module issue creating a info.php with this content <?php echo phpinfo(); ?> and place it in /var/www/html/ then access it in the browser like so localhost/info.php and check to see if that module is enabled.

sudo a2dismod php7.0
sudo a2enmod php7.3 

worked for me, I had installed php7.0 just before realizing I needed 7.3 and had to remove it but I had a feeling something was still referring to the old PHP, this fixed it.

I had the same issue, mbstring for PHP 7.1 was installed and enabled yet phpmyadmin was telling me otherwise.

We were both right, mbstring for 7.1 was installed but apache was running on PHP7.0 after the upgrade, so I swapped PHP versions...

a2dismod php7.0
a2enmod PHP7.1

restarted apache2 and all was good.

(this happened right after a release-upgrade to 17.10 which reported some issues)
