Site temporary unavailable

Hi,

since yesterday I got the error 

1 Sorry, site is temporary unavailable. Please try again later.

Funny; only the index site is broken. Every site else is working!? I dont found a solution until yet :-(

I would ask your host about this one.   

 That message is a template problem. Are you using a custom template?

I am using the standard templates of boonex. I modified the stylesheets an the images. Also the in the page builder the column size.

@mscott: Thanks for the tip. I found the bug in the page_1.html template.
