My page close down when I trying to make changes

[Annette Berntsson]

Hello, I have a page named news and now I want to change some on that page but I can only open it and in 1 minute the come up that is a problem and the page must be closed and then the Blue voda is closing the hole program.
I find some more pages on my site who also closes in 1 minute, so now I cant make any changes, what is wrong???
