Is downgrading an option?
No idea why this was UTTERLY FUCKING RUINED in a single update, but can I just use an old version? New version is the most confusing pile of shit plugin I ever had the misfortune of having to admin.

Please watch the language and attitude thoug...
Downgraded and back to working perfectly... No idea what or who version 5 is for? Seems like TONS of people can't get it work at all, or semi-right...

Sorry about that, but if you have 2 hours of your life stolen through no fault of your own, you tend to get a little testy...
I have rewritten a plugin so it's now more functional also all known issues are fixed in the latest versions. Configuration can be complicated for some people but there is documentation which explains at least something also you can ask questions here. What's the problem and why don't you like the update?
