Hi,
I have an update news for your ticket. To solved the problem, please follow these steps:
1. Open Notepad++ or anything can contain these code lines
2. Paste them into file

<div class="block block-shipping">
<div class="inner">
<ul class="list-shipping">
<li class="shipping-item"><em class="icon-plane"></em><a href="#"><span class="title">Free Shipping</span> <span class="desc">on orders over $49</span></a></li>
<li class="exchange-item"><em class="icon-refresh"></em><a href="#"><span class="title">1st Exchange Free</span> <span class="desc">on 3 days</span></a></li>
<li class="support-item"><em class=" icon-comments"></em><a href="#"><span class="title">Online support 24/7</span> <span class="desc">123 456 7890</span></a></li>
<li class="friends-item"><em class="icon-gift"></em><a href="#"><span class="title">Tell Friends and get $5</span> <span class="desc">a small gift for you</span></a></li>
</ul>
</div>
</div>

3. Save file as drafts. ( You have to edit it on notepad or anything but backend of Magento because Magento does not read the tag em)
4. Replace the links you want.
5. Go to backend >> CMS >> Static Blocks
6. Open block Position-10
7. Click [Show/Hide Editor] to hide editor bar.
8 Copy and paste the code from file draft into the editor
9 Click [Save Block]
Now the issue has solved. 
Hope this helps.
Best Regards,
