My Members have to Sign In twice ...

I already applied the fix from @Andy Millne here:
http://community.invisionpower.com/4docs/knowledgebase/407-sign-in-requires-two-attempts-r134/

i deleted:

Browser-Cache
Forums-Cache
OPCache

still nothing.

Any ideas?

I was having the same issue running Memcached, so I had removed it.  Since seeing that there is a patch, I have just re-enabled memcached and applied the patch.  Will post here if the patch works for my site.

 

The patch didn't work, still had to log in twice.

This issue will be solved in 4.0.8.

it works now with 4.0.8 and guest cache enabled
