Thesis theme multisite error

Hi, anybody ever had this problem?

I get an error message on one of my thesis theme blog. (see error message bottom)
They share the same wordpress multisite installation from the root. they all have their custom-1, custom-2, custom-3 etc…
All other blog work normally except one.

how can this happen to one blog since they share the same wordpress install.
I mean if their would be wordpress error in the installation the thesis theme would make the same errors on all of my other blogs?

the error message:
