Hi there, seemingly we have the same issue. But in our case the footer file is fine. The issue seems to be located in the Helpscout Beacon. We tried other Header, footer injection plugins. All ended up with same result. We have now deleted the HS Beacon script from the </body> tag. And forms are again showing. We did not have this issue until about 1 maybe 2 weeks ago. Except for general updates we did not change anything on our end.
Please advice, Thanks for your help
