php error using $cfg['ServerDefault'] = 0; on 5.0

[stultitiophobia]

after copying an working existing config.inc.php from phpMyAdmin 4.9.4 to the phpMyAdmin 5.0.1 directory phpMyAdmin 5.0.1 shows only a white page.
Running php index.php shows some error - perhaps that may help.

Running phpMyAdmin 5.0.1 without config works - generating a config from /setup leads to the same error...

Thank you for the report, I will look into it ASAP

Had the same error. Work-around for me was changing $cfg['ServerDefault'] = 0; to $cfg['ServerDefault'] = 1;.

@JarnoVgr @trendchiller you can apply 876b6e1 if you want to fix the issue before the snapshot is updated (phpMyAdmin 5.0+snapshot)

The fix will be part of the next release
