well I would first revert the the default theme! the theme you have is full of errors, and its causing the browser to crash. I just tried it myself. It can also be caused by a plugin!
so please turn off all plugins, and try the classic or default theme. No errors? well next step it to active one plugins at a time and look for errors. If all your plugins you want are ativated switch to the theme you want, which of course could be part of the problem.. Repeat the deactivation/activation of plugins until you find the horked up one.
Best of luck
FYI: Im not going back to your blog since I don’t trust what is going on ..
