Pages not loading

I had my website working – until I deleted all of the sidebar things – widgets (comments, posts and other things…) that I did not need. (as suggested by someone here – and it worked!).

But now my website is not working.

The menu tabs used to go to the right pages – but now it stays on the one page.

I made sure they were all linked properly. They used to come up. But after deleting the widgets – only the main page comes up.

I have tried everything and am spending a ton of time – but nothing seems to work.

I even went in and created a new page (just to test it) – and now I have even more problems.

I just went to “Edit” a page – and hit “preview changes” – and it brought up my Main Page – not the page that I was editing.

Every page that I go to – when I bring up preview = brings up the main page – not the page I am on.

Any ideas on what is going on?

Also –
Published Date/Time not changing. When I make a change to a page – and publish it – the date/time published does not change.

Any help would be really appreciated.
