Strange H1 : Javascript ES6 not supported

Hello,

There’s an invisible H1 (but visible for Google) in every page of my site dealing about : Javascript ES6 not supported
Here’s the document outline of my homepage : https://blog-peche.thefisherbox.com/wp-content/uploads/2020/08/issue-fisherbox-H1-JS.jpg
My blog : https://blog-peche.thefisherbox.com/

I think it’s related to Newspaper Theme because when i inspect the HTML code of my page i see this :

<div id=”tdb-es6-not-supported” style=”display: none;”>
<div class=”tdb-es6-wrap”>
<div class=”tdb-es6-content”>
<h1 class=”tdb-es6-title”>Javascript ES6 not supported</h1>
<div class=”tdb-es6-message”>This feature is not available on this browser. Please use a browser that supports javascript ES6:</div>
<table>
<tbody><tr>
<th></th>
<th></th>
</tr>
<tr>
<td>Chrome</td>
<td>(v49+)</td>
</tr>
<tr>
<td>Firefox</td>
<td>(v57+)</td>
</tr>
<tr>
<td>Safari</td>
<td>(v11+)</td>
</tr>
<tr>
<td>IE Edge</td>
<td>(v16+)</td>
</tr>
</tbody></table>
</div>
<div class=”tdb-es6-footer”>
<button class=”tdb-btn tdb-es6-close”>Close</button>
</div>
</div>
</div>

If you have any idea to remove this title, it should be great :).

Thanks

I have the same issue. Is there a fix for this? For SEO targeting, this is very alarming!

I am not using any tool. To see h1 tags on a page you don’t need a tool to see the source code.

This code shows up on all pages:

<div id="tdb-es6-not-supported" style="display: none;">
<div class="tdb-es6-wrap">
<div class="tdb-es6-content">
<h1 class="tdb-es6-title">Javascript ES6 not supported</h1>
<div class="tdb-es6-message">This feature is not available on this browser. Please use a browser that supports javascript ES6:</div>

I don’t know what that code is for. But the term “Javascript ES6 not supported” should not be wrapped in an h1 tag.

This was reported weeks ago.

Can you tell me what that code is for, and how I can stop it from being wrapped in an h1 tag?
