WordPress dashboard won't refresh after committing change.

Hey Gang,

I’ve been working on a new site for about a week without any problem.

But since yesterday, I’ve been having this weird problem.

When I make any changes (add a page, update a page, change the menu, etc… Basically anything that involves committing a change), dashboard does not refresh the page. All I get is a blank page… No menu, no nothing.

BUT, the change is saved when I go back to see manually.

I haven’t added/updated any plugins since the first login. I haven’t updated WP.

Anyone got a clue?!

Thanks

Phet
