Signing into WordPress doesn't signin to Vanilla
Whenever I press the signin button on my forum, it signs me into WordPress but it doesn't sign me into Vanilla unless I go to the forum page and press sign in (after signing into WP using the same button).
Is this a bug? I've set both cookie domains to .domain.com. Please help me!
