WooCommerce Cart WooCart Pro: Broken Plugin Fix

The core of WordPress is designed to be lean and lightweight while maximizing flexibility to prevent code bloat. Third party WordPress plugins offer custom functionality and features so that webmasters can tailor their website to their specific needs, but from our experience these third party plugins are very poorly written and require us to fix their code so the plugins operate properly.

This was the exactly the case when we purchased the e-commerce shopping cart plugin from Codecanyon called WooCommerce Cart – WooCart Pro.

Since the plugin was broken out of the box when we purchased it, everyone else must be experiencing the same functionality issues as well. Broken plugins can cause havoc to any website. Fortunately, our team of web developers have come up with a solution to fix this broken plugin.
