Upgraded from 13 to 14.1.1 (on-prem packaged Ubuntu 20.04) and when navigating from the web interface > admin > plugins, all the plugins are gone.

havin same empty page, but plugins working ok.

Hello Gerard and Alexander,

this has indeed changed with version 14.0 and is a result of feature request OP-14491. [1]
Only non bundled plugins appear in the plugins section now after the previous listing sparked confusion in some situations.
If you want to see all installed plugins you can do this in the rails console. [2]

In the rails console you can run the following command to show all installed plugins:

Redmine::Plugin.all

Best,

Alexander

Hello Alexander,

thanks for explanation, actually reasonable behavior not to show bundled modules.
