OK, the cause of the lines has been determined. There was a little snip of code which was at the end of the last paragraph on the page
I have no idea where it came from but it was causing the browser, perhaps due to doctype, to mess up what followed on the page thus the lines appearing. I removed that code and everything seems to be fine now.
This topic can be marked resolved.
I think that the Form is irrelevant because I’ve removed the widget and even deactivated Gravity Forms during my testing of this and the lines remain.
I think that the article you pointed to is more relevant to what is causing this than anything else. But I don’t know how to troubleshoot that. Clearly though something is causing the browser to go into an improper mode cuasing those lines to display on IE but only on that employment page. None of the other pages show the lines.
I’m pulling my hair out.
