If you're moving your site, you may need to export and then import your Social Link Pages. Here's how:
Before you move your site, export your pages.
To export your pages, expand the "advanced options" below your list of pages.
Click on the "export your pages" button.
A csv file called "social-link-pages.csv" containing all of your pages will begin downloading. You'll see a confirmation window to confirm your download has begun.
Save this file! It contains all of your Social Link Pages data for importing.
Once you've moved your site, import your files.
To import your pages, expand the "advanced options" below your list of pages.
Click on the "Import pages" button.
If you do not have any pages yet, you'll see the "create your first page" modal window. Click the "import pages" link at the bottom.
The "Import pages" modal window will open.
Select the "social-link-pages.csv" csv fie that you exported previously.
Then click the "begin upload" button.
Your pages will be imported, and the page will reload showing all of your pages.
Note: if you try to import a page with a slug that is already used by another page, it will not be imported.
