Order Form for WooCommerce version 1.6.2 has just been released. It fixes broken order forms on websites with no pretty permalinks.
I find it strange that an ecommerce website might not have pretty permalinks enabled; they’re integral to good SEO. It’s not unusual for a development website, however, and that’s where this bug showed up. If a developer tested this plugin with pretty permalinks turned off, they would find that order forms just wouldn’t work. Now fixed.
WooCommerce 2.5 was also released today, and I’m happy to say that Order Forms works well with the new WooCommerce. It also still works with older versions, so don’t worry if you’re sensibly waiting for a point release on WooCommerce! Certainly, that’s something I always recommend with major releases.
You can update to the latest version from your WordPress plugin admin page. Here’s the full changelog for Order Form for WooCommerce.
