Fatal error: require_once(): Failed opening required 'ROOT_PATH

[eehmke]

Describe the bug

After upgrading from 4.9.3 to 5.0.0 I got this error message:

Warning: Use of undefined constant ROOT_PATH - assumed 'ROOT_PATH' (this will throw an Error in a future version of PHP) in /var/www/phpMyAdmin-5.0.0-all-languages/libraries/common.inc.php on line 78

Warning: require_once(ROOT_PATHlibraries/vendor_config.php): failed to open stream: No such file or directory in /var/www/phpMyAdmin-5.0.0-all-languages/libraries/common.inc.php on line 78

Fatal error: require_once(): Failed opening required 'ROOT_PATHlibraries/vendor_config.php' (include_path='.') in /var/www/phpMyAdmin-5.0.0-all-languages/libraries/common.inc.php on line 78

When I downgraded to 4.9.3 the problem disappeared.

@eehmke something must be wrong on your configuration
Can you explain how you did install/upgrade/downgrade phpMyAdmin ?
Do you use a tool ?

[eehmke]

No tool. I installed the new version in a separate directory, copied the config.inc.php from the working 4.9.3 to the new directory, and switched the phpMyAdmin symlink to point to the new directory. Then the error message appeared immediately, no login screen. Switching back the symlink to the 4.9.3 directory solved the problem.
This procedure worked for me for all previous upgrades, and also worked for 5.0.0 on my other installation on another machine.

@eehmke Can you try "phpMyAdmin 5.0+snapshot" on https://www.phpmyadmin.net/downloads/ ?

If it does not work can you send the config.inc.php contents here ?

[eehmke]

The snapshot made no difference. Here is the config file:
config.inc.php.txt

And a screenshot:

[williamdes]

@eehmke You have something that breaks somewhere, can you send your php fpm config and apache config ?

• I downloaded the snapshot phpMyAdmin-5.0+snapshot-all-languages.zip
• unziped it
• saved your config
• phpMyAdmin is working on php 7.3

[williamdes]

@eehmke can you explain the process that you use to create the symlink ?
Do you have .htaccess files that configure variables ?

[eehmke]

Ok, here we go. Other vhosts deleted from the apache config.
ftv.conf.txt
www-pma.conf.txt

Symlink created by ln -s command.

@eehmke I will look at it in details in about 5 hours, can you check the permissions of libraries/vendor_config.php and other files ?

[eehmke]

# ls -l libraries/vendor_config.php
-rw-r--r-- 1 www-pma www-pma 2020 Jan  7 00:06 libraries/vendor_config.php

www-pma is the owner of the complete directory. www-data is in the group of www-pma.
