Search not working & Saving Posts

Hi

This issue started yesterday and I can’t figure out why.

When I’m in Wordress (not my website) in All Posts and type in a keyword to try and find a particular post, I hit Enter and it just goes back to the same list of all posts. Doesn’t matter what keyword I type, all posts comes back, not any in particular.

Second issue – when I’ve finished a new Post and click Save Draft, it comes back with a totally blank post – as if everything has been deleted and not saved. When I go back into All Posts though, it HAS saved.

I haven’t installed any new plugins in the last few days, I have the updated version of WP and it’s coming up with the issue on Google Chrome and IE.

Any suggestions welcome please as this is really annoying!
