[support] View stopped working....

Hello,

I have a very strange problem on a live site, all views that display content types other than "page" return nothing.

The site has been working great for about a year, today I deleted a page node, change a filter in a view and change a filter in a block and then the client reported that none of the views work.

After checking and trying to fix, I can't get a view to return nodes that aren't "page".

I created a new view, with just one filter according to node type. Set it to just page, returns great. Set it to all except "page" and nothing.

What can cause this?

This is pretty urgent.

Thanks

Idan
