TOPIC: CSS not loaded after clicking on page navigation

I have edited the template file and created a styling for the page navigation. However, the style is lost when I clicked on the pages to navigate. I'm using <li> to perform the styling.

This happens when I'm using with Ajax-support.

Page on first load:



Page style error after clicking on link:

do you have li class="test" or li class='test' - the second one with single quote is right.
