Thank you for adding the "This Month" and "This Year" filters and navigation in recent ES update.
The links on the "This Month" one don't seem to be creating correctly though... have supplied a link to it on my site... it's the "forward" and "backward" arrows at the top... the "forward" one links to the same month already being displayed and the "backward" one seems to go back 2 months.
(The behaviour on the "This Year" filter seems to be working fine)
