Strange Issue with webdevops/php-apache and phpmyadmin (Blank page after config, no errors)

[LeeThompson]

Apache & PHP are working fine for the most part, but when I tried to put phpmyadmin on with my other "web apps" I get a blank page after phpmyadmin is configured (before it's configured, it executes fine).

I'm completely stumped, I've checked everything I can think of. If I try to execute phpmyadmin's index.php in a Docker terminal window, if the config is there it doesn't error it just does nothing, if the config file isn't there it spits out lots of stuff.

To double check the config, I added a "var_dump($cfg);" to the end of it and ran it in the terminal window and got the output I expected.

No idea. 0 bytes are sent back to the client.

No errors anywhere.

phpMyAdmin 5.2.0 Synology DSM 6.2.4 image: webdevops/php-apache:latest

UPDATE: I just noticed :latest hasn't been updated for 3 years. I'm going to try to swap images to :7.4 UPDATE 2: Nope, exactly the same on image: webdevops/php-apache:7.4
