Good evening George and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the issues you have faced while trying to integrate our plugins with Qtranslate. I would love to help you with this topic.
Unfortunately, we do not support Qtranslate.
However, the good news is that we officially support WPML for multi-language sites: https://theeventscalendar.com/knowledgebase/wpml-support/
The other good news (although unsupported officially) is that several of our customers have also achieved satisfactory integration with Polylang.
I wish I had a better answer for you, but for now it’s the best one I have unfortunately.
Best regards,
Geoff B.
