I'm now seeing this symptom on several projects in the 'latest' release branch. Such as:


My browser exposes the following error:


We patched [1] our project as a workaround.

Could one of Stephen's commits [2] be involved?

Hi, I'm hitting an oddity in one of my projects where the titles of all pages show up twice.


Source file is here:

Does anyone see what can be causing this? It appears to happen only for the current stable release ('wallaby') and 'latest'.


I suspect you're bumping into issues introduced by a new version of Sphinx or docutils (new versions of both were released recently).

Comparing the current nova docs [1] to what you have, I see the duplicate <h1> element is present but hidden by the following CSS rule:

.docs-body .section h1 {
    display: none;

That works because we have the following HTML in the nova docs:

<div class="section" id="extra-specs">
    <h1>Extra Specs<a class="headerlink" href="#extra-specs" title="Permalink to this headline">¶</a></h1>

while the docs you linked are using the HTML5 semantic '<section>' tag:

<section id="nova-cells">
    <h1>Nova Cells<a class="headerlink" href="#nova-cells" title="Permalink to this headline">¶</a></h1>

So to fix this, we'll have to update the openstackdocstheme to handle these changes. I can try to take a look at this next week but I really wouldn't mind if someone beat me to it.
