This plugin is not working at all on my website. I tried it with different versions of WP and WC, older and newer, and it doesn't work. The customer support department tried to help, but did not find a solution for this problem, their only solution was to changee the hosting company :) I had no problem with any other plugin on this hosting company. So, with no solution for this plugin, they refused to refund. Never had any problemwith other items on Envato market.

More than 300 sites are using this plugin and your Hosting is the Only hosting which imposed such restrictions on Ajax calls, not sure how could we help in such cases, when the hosting server has issues. You could easily switch to any other hosting and even you also saw at your development environment that the item works fine. But again your hosting is the one that caused the issue, even though you realized the issue, however you are blaming the item. People should really be more sensible and should take proper steps when they already know the cause of the issue, instead of blaming innocent item. Thank you.
