I had the same problem – 500 server error after updating to Woocommerce 2.2 on WordPress 3.9. All my plugins were up-to-date I stress.
I solved it by:
Using ftp or cpanel folder access delete the Wocommerce folder (wp-content/plugins/woocommerce)
Download the latest version of Woocommerce (at the time v2.2.1), extract and upload to the plugins folder.
Hey presto, problem solved.
Hope this helps someone.
Instagram only allows the adding of new content from their own app (iOS / Android / Windows Mobile).
Third party apps and sites can manage likes and followers but not images or video.
Most tedious.
