404 Error 'Newest Photos' and 'Most Viewed Photos' 404 error

I am using Gallery 2.3.1 with the theme Ebony here

I am getting a 404 error when clicking on 'Newest Photos' and 'Most Viewed Photos'.

I have read the instructions on how to fix in the forum i.e.

To make the "Newest Photos" and "Most Viewed Photos" links work:

First, you will need to have the URL REWRITE plugin installed and activated.
In the URL Rewrite config page (Admin section of Gallery), make sure the dynamic albums are created like they are in this post:

The URL REWRITE Plugin is not installed and after clicking on install cannot comprehend the instructions ???

Below I can follow:

Load file "sidebar.tpl" from its location the templates folder.

Scroll down to line 17. You will see:

<li><a href="/updates"><strong>Newest Photos</strong></a></li>
<li><a href="/popular"><strong>Most Viewed Photos</strong></a></li>

Change the href to reflect your path to your gallery.
I simply put a period in front of the slash to make the path relative instead of absolute:

<li><a href="./updates"><strong>Newest Photos</strong></a></li>
<li><a href="./popular"><strong>Most Viewed Photos</strong></a></li>

Can someone help - thanks
