Hi,

You can install the attachment extension by extra zip code to the ROOT. After that, please go to the CMS >> Pages, choose the page ‘home page’ which you are currently using. Click the tab ‘Design’, and find the code

<block type="twitter/list" name="twitter.list.default"></block>

Replace this by:

<!-- <block type="twitter/list" name="twitter.list.default"></block> -->
 <block type="facebook/list" name="facebook.list.default"></block>

Best regards,
