Yes, I forgot that I had modified my theme as well (fonts and what have you) and had to redo it all over again.
Thing is, as far as I can tell, there is no reason for this update other than they changed the link back to their site in the footer.
No idea why it made it crash, but I tried it once again, just to see, and sure enough 1.0.14 breaks it, and 1.0.13 fixes it again.
I was hoping that the creator of this theme would see this message and issue a fix.
Since they did not, here is what I did:
I went to this site:
http://themes.trac.wordpress.org/ticket/4075
I downloaded the 1.0.13 version.
I unzipped it on my home computer.
I use my FTP program (Flezilla is free if you need ftp software)
to go into:
Domain/install directory (if you have one)/wp-content/themes/showcase/
and then I uploaded the 1.0.13 version ontop of all the files in that folder. I just let it replace every file, rather then trying to figure out which one has the problem.
Hope that helps tjuras.
