Upfront editor is showing raw HTML.

When I try to add a URL to text in a text element in my footer region, Upfront displays the raw markup. It also randomly decides to show formatting markup like <span>, usually with a mention of 'redactor' somewhere in it. Deleting and rewriting does not fix the problem.

I tried to submit this question through the web site, but could not because the form on the web site requires

"You must read and check "I have read The Good Support Ticket tutorial" option."

No box appears in Mac Chrome or Firefox.

I have screen shots if you need them
