Hi Jason,
Sorry about the delayed response. I’ve been sick. (It’s been awesome!)
It seems to be working perfectly on your blog. (postmatic)
1. Chrome Version 63.0.3239.84
2. Windows 7 (I’ve also replicated this issue on Windows 10)
3. Wordrpress, Google, Twitter, Facebook (Does not work with any)
4. Blank white window (same size as functioning login window.) with a single 0.
I reinstalled the plugin on the site I’m struggling with so that you could see the behavior. Check out this blog post: https://www.soundchecked.net/2018/01/01/new-years-day-u2/ I’ll leave the plugin operational while we work this out. Thanks!
