The columns attribute does not work

Created by: rplCloud

For a while the columns attribute does not work on my wiki.

I just get very long lists. The table tag is missing completely.

Wiki Source

=== Extensions ===

{{#dpl: | columns=3 | rowcolformat=class=dpl | suppresserrors=true | ordermethod=sortkey | order=ascending | namespace= | category={{PAGENAME}}&Extension | notcategory=Python}}

HTML Source

<h3><span class="mw-headline" id="Extensions">Extensions</span></h3>
<ul>
<li><a title="Cite" href="/wiki/Cite">Cite</a></li>
<li><a title="DynamicPageList" href="/wiki/DynamicPageList">DynamicPageList</a></li>
<li><a title="DynamicPageList3" href="/wiki/DynamicPageList3">DynamicPageList3</a>
...
</ul>

Can you verify this behavior?
