After resetting the position and publishing, the buttons don't show. The position fields are empty after publishing.
Thanks for letting us know about this! We found a bug with the position setting in the dashboard and have fixed it. An update will be release as soon as possible! 😄
But it seems that this might not be the reason as to why Buttonizer is not showing up after updating.
We have another similar support question in our mail and it seems to be caused by their minifying plugin.
It had cached/minifed the older version of Buttonizer on the frontend, causing it to act weird.
Could you perhaps let us know which caching/minify plugin are you using on your site?
We would like to test it for you and see if we can reproduce the problem on our end. 😁
