Hey there
So sorry for that mix-up. I do see 2 licenses for Event Tickets Plus, activated on different sites. Verifying this is what you wanted as you mentioned you had uploaded one previously.
When you uploaded your plugin to your site, did you start by uploading the plugin with the license activated on that site? Or did you possibly upload the version already activated on another domain?
Could you share a screenshot where you are seeing this message?
Could you go through our Testing for Conflicts guide: https://theeventscalendar.com/knowledgebase/testing-for-conflicts/
When you are checking for Event Tickets Plus, please remove it from your site, then download it for the crrect domain from My Account ยป Downloads https://theeventscalendar.com/my-account/downloads/ and upload it again to your site.
Please let me know if the issue persists after this.
Thanks
Courtney ๐
