WP Polls problem with cloudflare

Hi fellas, we have an amazing portal trough wordpress.

We have around 20k visits/day

So i put cloudflare to work, cloudflare + sunny plugin,

Works wicked! but i think makes my problem with wp polls start.

when the visitors click to vote still loading and after shows: Failed To Verify Referrer

I put cloudflare to cache everything, using my 3 free rules on cloudflare.

Can i fix this problem without deactivating cloudflare ???

thanks in advance!!!!
