Open tpl_page_nosidebar.php
In line 32:
<div class="wp-pagenavi"><?php wp_link_pages('before=Pages: &pagelink=<span>'%'</span>'); ?></div>
replace with:
<div class="wp-pagenavi"><?php wp_link_pages('before=Pages: &pagelink=<span>%</span>'); ?></div>
So basically you are removing the ‘ before and after the % between the span
tags.
I’m not sure if that is the actually fix but I removed them and the page displayed properly after.
