If I install this bugfix, then I get a blank screen, if I set the Postpage under Settings/Reading to a site different from the frontpage.
You to let you guys know.

Thank you for a great theme!!

What version of Atahualpa are you using - all BUGFIX 364-nn are for version 3.6.4 only

I set the Postpage under Settings/Reading to a site different from the frontpage

do you mean you point the frontpage at a different PAGE? not SITE?

Sorry!!!!
My mistake. I am using 3.6.7 and got the wrong bugfix. I found the right one and it is working perfect!

And yes, I did mean page :-)

Thank you so much!!!
