I installed Hummingbird this morning and was going through the various settings. All was going well, until I went back on my site to make some changes in a page. I'm using the Beaver Builder Page Builder plugin, and it would not work as long as Hummingbird was activated. I tried this in two browsers, Safari and Chrome.
I've used Beaver Builder with a large number of plugins on a variety or sites and have not run into this issue before. Have you had other reports of this?
