There is often problem to turn off the plugin

[anonymous]

Eg. after restart screen with app by fgci I can't turn off plugin by plugin manager as admin, must do this by trac.ini only

Error: Unable to check for upgrade of tracusermanager.api.EnvironmentFixKnownUsers:
TypeError: environment_needs_upgrade() takes exactly 2 arguments (1 given)

• many not updated plugins doing this type problems

PluginIssue: ​UserManagerPlugin.

Please report to the plugin author or report these issues on the MailingList for better help. They should not be reported in this issue tracker.

Trac is not responsible for the maintenance of plugins. Please take care before installing unknown plugins. The plugins may be unmaintained and may prove to be unreliable.

But it's not about UserManagerPlugin, just example..

[Ryan J Ollos]

The plugins raising those errors have not been updated to use the latest Trac API. The plugin is at fault.

But this reason to implement solution to prevent this case when plugin is old or not compatible, to easy turn off. Admin trac not always is admin of server, where not have acess to trac.ini, the panel and GUI web should be enough to manage addons, etc.

We understand, but the management of plugins in the Admin panel is a Trac design decision.

We improved the behavior in #12680. I'll need to take a look at this case to see what is going on.
