On Jenkins 1.635 I am trying to use the Plain Credentials plugin version 1.1 to store an API token as a credential. However in the Plugin Manager the "Enabled" box for this plugin is not checked. I also cannot check the box. When I hover over it, I get a message saying that it cannot be disabled because some other plugins are using it.
Any suggestions on how to get the Plain Credentials plugin enabled?
Thanks in advance.
