W3 cache giving ajax 500 errors for Gravity Froms

Hi There,

I’m having issues with W3 total cache and Gravity forms. When creating new forms in Gravity forms admin page I get an ajax 500 error.

This only happens when caching with W3 total cache is enabled. Is there a way to allow ajax to run for Gravity forms?

Thanks
