From there a slide should come up to your left of the screen >
(This screenshot wont capture the inspect element)
Hover over one of the options within the red box, as shown in the screen shot.
Hovering over it should highlight it in the inspect element drawer >>>
What you're going to do is basically copy the code that is provided
Code:
<li>
<td valign="top" width="1">
<input type="checkbox" class="checkbox" name="classicpostbit" id="classicpostbit" value="1">
<label for="classicpostbit">Display posts in classic mode.</label>
</input>
</td>
</li>
Then hover over one of the thread options, open the code that is highlighted in the inspect element by right clicking and picking "Edit as HTML", the whole code translation should pop up in the box below. Select everything in that box, delete it and paste the code im giving you in there.
Now click on website, and it should update with a new box "Enable Classic Mode", click that and update the settings.
