did you look in the widgets?
Hey have you checked out the page template file that, that page is using? It would most likely be in there or in a required php file that that page template is calling. So my advice in lamens term is if you don’t know how to tell which files are controlling the page template first … post the name of the page template here and I’ll try and help you figure it out :).
Or like janet4now said it could be in a widget. However the way that code is appearing makes me think it’s in the actual page template file. I could be wrong though. I have been wrong in the past … 🙂
I would have to agree with janet4now. It looks like a widget issue. Check your widgets for a widget with the Contact Form 7 shortcode. Most likely the shortcode needs to be corrected to match with a current form.
Yes, in the code it shows it as a “text widget” with a 404 not found.
