Livemap not working?

I went on live map today to discover it's not working..... Any help?
Whenever I open up the map it just gives me a black screen with a red box at the top that says:

Web files are not matched with plugin version: All files need to be same version (1.7.1-714) - try refreshing browser cache (shift-reload)

EDIT: It is only not working for Smp9. All other servers work fine.
Why is this happening?

Works fine for me...

I was just using it half an hour ago... Worked fine.

It did this for me right after we updated. I think what fixed it was to clear my cache.

Livemap is working fine for me

How do you clear your cache? Sorry I'm horrible at this xD

xD
Internet Exploder: Tools>Delete Browsing History> Click the cookies box.
FireFox: Tools> Clear Recent History > Click the boxes.
Chrome: Click the Menu button that looks like 3 lines by the address bar> History> Clear Browsing Data

That worked, thanks!
Will a mod please close this thread now, as it is useless.

Locked as requested by OP.
