You are missing the css. Add this to your css.
.pagination ul{
display: inline;
}
.pagination ul li{
margin-left: 0;
padding: 3px 5px;
color: #2b6b97;
list-style: none;
display: inline;
font-size: 1.2em;
font-weight: bold;
}
Try this
Open core/classes/CodonModule.class.php
Right after <?php on a new line add
ini_set('error_reporting', E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED);
Who made the theme? Someone with the same theme has the same issue. Also you are using Bootstap. Than can cause a conflict. There is a css from another theme in there too.
