How to find out more when "Enable" button fails with no error
I'm using 126.96.36.199 and trying to install Vanilla API 0.2.0. I hit "Enable", it tries briefly, then reloads the page. There are no error messages. I'm wondering what the significance of this is, and how to best find out more details about what might be going wrong. (Not looking for Vanilla API help, just wondering what to do when this sort of 'Enable' issue happens.
