Can't enable or remove plugin

[kedare]

Hello.

On a new Piwigo setup (v12.1.0)

I can download the openstreetmap plugin (same behaviour from doing a git clone also), but when activating it, I get an error and this in the logs

2022/01/26 17:38:02 [error] 3981935#3981935: *29001 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Class 'piwigo-openstreetmap_maintain' not found in /var/www/piwigo/admin/include

Same error when trying to uninstall it

Any idea on how to fix it ?

Thanks
