I have got a clean build (WordPress 3.9.1 running Twenty Fourteen theme).

I’ve installed WooCommerce plugin and added one product.

The product is a variable product with 65 variations.

When I link all variations and save, there are no issues. But editing any information such as stock quantities or price etc and hitting Update will cause the problem below.

Once I click Update, I am redirected to edit.php (the Posts page) and the changes were not saved. There is no error and everything seems to be running just fine.

Upon removing variations one by one I realised that once there’s less than 50, the post updates perfectly.

I’ve tried increasing memory in PHP.ini, .htaccess, wp-config.php and nothing.

Any ideas at all as I’m absolutely lost on this one.

Many thanks in advance.

Michael

EDIT: In actual fact, you don’t have to even attempt to change the properties of the new product. Even just trying to change this as it is will cause this issue.
