$R['link_pagenav_gap'] = '';

but not the other one. So now there are no dots :)

Added 10 hours later:

By the way....
Is there more of these $R things that one can use?

$R['link_pagenav_gap'] = '<li class="disabled">...</li>';

or remove dots:

$R['link_pagenav_gap'] = '';

They are wrapped in this:

<ul class="pagination">{LIST_TOP_PAGEPREV}{LIST_TOP_PAGINATION}{LIST_TOP_PAGENEXT}</ul>

and the output is this:

<ul class="pagination">
<li><a href="https://www.cotonti.com/music">&lt;&lt;</a></li>
<li><a href="https://www.cotonti.com/music?d=9">&lt;</a></li>
<li><a href="https://www.cotonti.com/music">1</a></li>
<li>...</li>
<li><a href="https://www.cotonti.com/music?d=5">5</a></li>
<li><a href="https://www.cotonti.com/music?d=6">6</a></li>
<li><a href="https://www.cotonti.com/music?d=7">7</a></li>
<li><a href="https://www.cotonti.com/music?d=8">8</a></li>
<li><a href="https://www.cotonti.com/music?d=9">9</a></li>
<li class="active"><a href="https://www.cotonti.com/music?d=10">10</a></li>
<li><a href="https://www.cotonti.com/music?d=11">11</a></li>
<li><a href="https://www.cotonti.com/music?d=12">12</a></li>
<li><a href="https://www.cotonti.com/music?d=13">13</a></li>
<li>...</li>
<li><a href="https://www.cotonti.com/music?d=50">50</a></li>
<li><a href="https://www.cotonti.com/music?d=11">&gt;</a></li>
<li><a href="https://www.cotonti.com/music?d=54">&gt;&gt;</a></li>
</ul>

You can clearly see that there are:

<li>...</li>

embedded at 2 locations, yet all ... (dots) are show in the end of the whole row of pagnation numbers as seen on the image below. Highly annoying!

I'm using the Siena 0.9.18 with Bootstrap v3.3.2. See the issue live here: http://www.evlear.com/music?d=10
