After today's maintenance, when I visit certain pages, I see a header at the top of the page that says, for example, Add a Skill to Tasala.

Here's that part of the page source: 

<div class="page-heading">
          <div class="page-heading__prefix">
            
          </div>
          <div class="page-heading__content">
            <h1 class="page-title">
              Add a Skill to Tasala
            </h1>
          </div>
          <div class="page-heading__suffix">
            
          </div>
        </div>

I'm seeing that header on the current create-thread page, my private-messages page, the search page, and the spells page. 

I do not see that heading on the main forums page or in any of the sub-forums or threads.

I see a different header on the classes page:

<div class="page-heading">
          <div class="page-heading__content">
            <h1 class="page-title">
              fey prone
            </h1>
          </div>
        </div>

The feats page has this header:

<div class="page-heading">
          <div class="page-heading__content">
            <h1 class="page-title">
              Animals
            </h1>
          </div>
        </div>

I'm seeing a different header, so it looks like there's some kind of site code cross contamination going on

Yes, I'm seeing different headers across the site. Most have a "Display in VTT" button.

Yep.  I assumed some sort of defect in the site's components.  I've adjusted the thread title to reflect the fact that it's some sort of bug with that page-heading. 

When I revisit the pages that I mentioned in my original post, I still have a contaminated page-heading element, but the text of that heading is now different.

This one is...impressively bizarre.

It seems to only show up when I'm logged in.

Seems to have maybe gotten sorted out now?

Thanks for taking care of that so quickly!

Thanks!
