Page error when changing style

[crl]

I changed the style from classic to mac osx and now have a page error!
I cannot gain access to the config panel to revert the style back.

Page Error:
"Template error

Thanks for the information.
Luckly I found an older thread which helped me get back into the classic template style.
So if anyone has a similar problem try accessing your site with the following
wwwmysite.com/gallery/login.php?theme=classic
you will then be logged in with the classic theme, well it worked for me!

You should upgrade your themes anyway - it looks like you haven't performed the upgrade as suggested.
