How to Fix Newer Older Post Navigation?

Yesterday, Im shocked by hidden older and newer post navigation. Actually I dont know why it's happened because my template (also on this blog) display properly since I create it.

Why my newer and older post navigation is hidden or display unproperly? How to solve this? I have tried to edit CSS code. Fortunately, it works.

Follow this step.
1. Open edit HTML
2. Check this section code
#blog-pager {
text-align: center;
}
3. Insert clear:both; code so the code will be look like this
#blog-pager {
text-align: center;
clear:both;
}
4. Save

Hope this work on your template too.
