Hi,

I have 3 Droplets all with ubuntu 18.04, Php 7.2.24, phpmyadmin ver. 4.6.6. Until yesterday phpmyadmin worked fine, but now it gives me HTTP Error 500. Otherwise there is nothing wrong with the servers - (not that i know of). Has anyone experienced the same?.

I have no problem using heidisql

Is there a safe solution to fix the problem. One of the servers is in production, and vulnerale to downtime.

SOLVED!!

After many hours i finally found what was wrong.

In /etc/phpmyadmin/config.inc.php last line there was a “;” missing

$cfg[‘TempDir’] = ‘/usr/share/phpmyadmin/tmp’; <-- ;

Can anyone tell why is this so that the phpMyAdmin server working perfectly fine yesterday suddenly misses a semicolon in the code? Would be great to know the reason.

Hello there! I am totally new in this world but everything can be done if you are able to search in the web.

I followed the tutorial given here in DO “How To Install phpMyAdmin From Source on Debian 10”, my mistake was to copy the code

" . . . $cfg[‘blowfish_secret’] = ‘STRINGOFTHIRTYTWORANDOMCHARACTERS’; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */ . . . "

First I got an error that xml extension was needed, so I installed it. #sudo apt install php-sml

then I restarted with: #sudo systemctl reload apache2

Then I got the error 500 described in this topic, so I found when I edited the config.inc.php file that the three dots (after " IN THIS FOR COOKE AUTH! */ " were copied too. I deleted them and worked right away.

I wish could help others

Kind regards to all!

and happy coding
