I can confirm this with the official distribution of 4.8.4.

From RELEASE_4_8_4, I get the error if I use composer install but not if I use composer upgrade.

The broken distribution uses pragmarx/google2fa v4.0.0, it works with v3.0.3.

I believe this is introduced during the release process in https://github.com/phpmyadmin/phpmyadmin/blob/master/scripts/create-release.sh#L239-L241 where there is no version constraint on these packages.

The proper fix for this is to make a change to our build script, which has been done in master. The result will be that the next release will fix this issue. It's a little confusing because the problem occurs in the 4.8.x branch (QA_4_8), but is really caused by the build script in master.

Anyway, it will be fixed with the next release, you can test it using the daily development snapshots at phpmyadmin.net (starting about 20 hours after I post this, because today's build has already run).

FWIW: There may still be a build issue... I tried installing the English only zip and could not enable 2FA.

When I installed the all-languages zip, I was able to enable 2FA.

@fallingrock perhaps you're seeing the same effects as #15017. Which phpMyAdmin version did you download that didn't work, 4.8.5?

Hi!
I have resolve the problem in my case.
I was using:

• Phpmyadmin 4.9.0.1
• pragmarx/google2fa:5.0.0
• pragmarx/google2fa-qrcode

When i tried to enable TwoFactor Authentication, i have the following error:

Fatal error: Uncaught Error: Call to undefined method PragmaRX\Google2FA\Google2FA::getQRCodeInline() in /home/vagrant/Code/lastphpmyadmin/libraries/classes/Plugins/TwoFactor/Application.php on line 99

To solve this problem, I uninstall the package pragmarx/google2fa-qrcode and worked fine!
