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.


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.

  • Try deactivating all plugins. If that works perfectly, then it's because of some plugin, which is off topic here: help center – тнє Sufi Jun 17 '14 at 14:49
  • The only plugin that's installed is the WooCommerce one. I've recreated this issue with a brand new install. I have a funny feeling it's to do with Wordpress set up though. – Mike_Piercy Jun 17 '14 at 14:53
  • Try to save a post after deactivating woocommerce. – тнє Sufi Jun 17 '14 at 14:55
  • WooCommerce uses a 'Products' as a custom post type. If I deactivate it then I won't be able to edit the post...? – Mike_Piercy Jun 17 '14 at 14:58
  • Try increasing post_max_size in your PHP ini – TheDeadMedic Jun 17 '14 at 14:59

For anyone looking for an answer on this, I found that setting the max_allowed_packets to 32 helped as well as turning off mod security on the host side. I hope this helps.
