Hi johnwick 
,
Welcome to the Buttonizer community!
Are you perhaps using All in one WordPress Security on your website?
We've had a couple of people here in the forums encounter the same error and it seems to be the cause of the issue so far.
All in one WordPress Security disables an URL GET parameter that Buttonizer uses in the backend.
Here's the topic where @kmzerowebmarketing solved the issue.

SOLVE: the problem was on the firewall settings, "6G Firewall protection" enabled still lock buttonizer admin functionality.
Let us know if it's All in one WordPress Security!

We have updated Buttonizer to version 2.0.6, the plugin All in one WordPress Security should be no longer a problem!
I'll mark this topic as solved
