Hi Grzegorz W
Thank you for getting in touch. Our sincerest apologies if our plugin caused any issues on your site and would be more than happy to assist you in sorting this out.
We weren’t able to find any communication from you regarding this though. In future, please can you rather leave a support request before posting a one star review. A one star review negatively impacts our average review score considerably and jeopardizes our plugin and business.
We do everything in our power to make sure things like this don’t happen, but sometimes it’s completely out of our control.
If possible, please get in touch with us via our contact form here: https://wp-livechat.com/contact-us/
Kind Regards,
Jarryd
