No, i have this theme ( original ) installed to 7 sites, checked them all and noone of them have the same.

www.familjegodis.se  (change to X-Mas in the theme box )
www.septaldefects.org  (change to X-Mas in the themebox )

This is 2 sites, but the other 5 i have show the same, no issues

I told you that I get the error on all themes, even on the default.

An update: the blank space is now showing on all pages, not just the index. It's also on the forum...

Then it must be some other mod you installed, it's not TP though

Replace all files with a fresh set from SMF and go from there.
