Can anyone tell me what this means?

Waing: Creating default object from empty value in /var/sites/e/elensentier.co.uk/public_html/wp-admin/includes/post.php on line 632

And how is it rectified?

thanks
Elen

what did you do before you got this error?

Pressed Add New.

What are you actually asking me?

Here is a general post about this. http://davebuesing.com/quickest-possible-way-deal-php-error-wordpress-blog/

He explains on how to remove it. But at end of article he does mention following: I’d start with the likely source of your problem, your server’s recent upgrade of PHP that you ignored because surely nothing would go wrong.

If you were not seeing it before and you didn't make any changes in code, it could be a PHP version issue on your web hosting site.

thanks for that Hema. I'm sending it on to my host as I'm guessing (???) it's their PHP problem. I've no idea what PHP is as I'm a writer, published author, and don't have time with deadlines to lea geek :-). I hope they know what's wrong ... thanks again, here's hoping!
