Update to latest Matomo 3.14 failure: Class 'Piwik\Plugins\UsersManager\Model' not found

[47k]

Hey guys

Today I upgraded via the on click updater from 3.xx (I think it was 3.12 or 3.13) to 3.14 and I got this issue directly after I clicked the button:

Class 'Piwik\Plugins\UsersManager\Model' not found

And this when I try it via CLI:

Hi @47k. Sorry to hear you had a problem while updating. The file that is missing in your case, should have actually already existed before. To fix the issue, maybe try reuploading Matomo using the latest release zip.

@sgiehl
Thank you for your answer. I have no idea if the file exists before, but I tried already the manually upgrading with the latest release zip. I uploaded and unzipped it und tried the "php /var/www/matomo/console core:update" command.

@47k Did that fix your problem?

[47k]

No - I tried that before and that's the point where I got the issue log from.

[sgiehl]

Just checked the latest release, and that file is definitely included in the ZIP file. Are you using some kind of PHP cache like APC or OPcache?

[47k]

The file is in - but the error is more that "ERROR [2020-07-21 09:57:51] 3635 Uncaught exception: Error: Class 'Piwik\Plugins\UsersManager\Model' not found in /var/www/matomo/plugins/Login/Auth.php:35"

In the file there is:
33 public function __construct()
34 {
35 $this->userModel = new Model();
36 $this->passwordHelper = new Password();
37 }

[sgiehl]

That's the point where it tries to load the model. But there should be a use statement for it, and the autoloader should then include the file. Not sure why the autoloader fails at that point 🤷

I tried again with reloading my virtual machine snapshot and now

unzip -o matomo.zip

worked for me.

[sgiehl]

Glad to hear it's working again for you. Will close this issue as I guess there is actually not much we can do on our side to prevent such problems.
