A little background. I inherited the site using this plugin. I did look at the plugin code first and it looked very straight-forward. Then I looked at the HTML page containing the final form. Apparently the final form is generated by the Elementor / Elementor Pro plugins using input from the Contact Form DB plugin.
If anyone recognizes the error and can help I would appreciate your insight. However, I can see that unraveling this is challenging since there are several layers of plugins involved and I’m not prepared to work out which plugins are actually in play.
Thanks.
