Question

http error 500 after installing phpmyadmin. Digitalocean

Hi! I need help accessing /phpmyadmin. Have not installed it before on an IP adress, since I’m new at DO and have only been playing around in localhost. I just deployed my site and where supposed to access my database through phpmyadmin, but got stuck at a http 500 error. Thankfull for all the help I can get.

We did a new systemlink: sudo ln -s /usr/share/phpmyadmin/ /var/www/html/phpmyadmin

We restarted nginx: sudo service nginx restart

ipadress/phpmyadmin: “This page isnt working” http 500 error”

Search for error: tail -f /var/log/nginx/error.log

Error we got:
#0 /usr/share/phpmyadmin/libraries/classes/Url.php(206): PhpMyAdmin\Url::getArgSeparator()
#1 /usr/share/phpmyadmin/libraries/classes/Url.php(169): PhpMyAdmin\Url::getCommonRaw()

We have gave this phpmyadmin folders these permissions: chmod 755 -R /usr/share/phpmyadmin chmod 644 /etc/phpmyadmin/config.inc.php

I struggled with this problem for an entire week. Fortunately, I was able to find the solution.

First Install MBSTRTING exension for your PHP Version. eg

Do

sudo apt install php8.0-mbstring

It will tell you to install MYSQLI extension for your PHP Version

Do

sudo apt-get install php8.0-mysql

Have a great day!

You need install php extension mbstring

Hi @Civalero,

It seems like there is a PHP error in the code which is very strange. What I’ll suggest you to do is delete PHPMYADMIN and re-install it. If there are any PHP errors you might need a developer to look at them otherwise you might end up in a rabbit hole resolving one error after another.

I’ll recommend giving the following tutorial a read:
