WordPress Page Revision Number Not Changing

Hi,

I’ve now tried disabling all plug ins and the clearing the cache but my wordpress site still isn’t updating the number of revisions and therefore not saving the changes.

What’s happening is every time I press ‘Update’ on a page, the page refreshes as normal but the number of revisions doesn’t. It’s stuck on 19 despite me making the changes and updating.

A friend of mine says he didn’t have the same problem on his Safari browser so then I switched from Chrome to Safari but still had the same problem.

I have a few changes to make until the site is live but I really need to solve this problem.

Any advice appreciated.

Thanks
