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.
