I run a website where we have 29 kids who have experienced the Tohoku eathquake and tsunami in Japan take pictures of their surroundings. It's an ongoing project in its third year and our site is currently down and in need of help.

Our wordpress website has gone blank except for the middle part of the bottom screen. I imagine it could be a cache related problem but I am unable to find out why and how to fix it.

When I install a new theme, the site changes on preview, but the changes isn't shown after activation.

I am very desperate, and your advice would be much appreciated.
