We followed graynoise’s suggestion to deactivate the Async JavaScript plugin. We found it in our theme although we didn’t put it there. The deactivation did seem to help by eliminating some of orange box errors. Unfortunately, not all browsers work.
It seems strange that the developer is not responding to any of our issues. There has to be an integration issue between Contact Form 7 v5.1.4 and ReCaptcha v3.
