Hi,
Here is how you can create footer rows and blocks in the new application
First off check the advanced footer main settings.
Customization -> Advanced footer -> Settings -> Configurations - > Who can see?
Check the "who can see" here and make sure that everyone can see it.
After that you need to create footer rows and blocks, and it is quite easy. just like forums when you create Categories and then forums inside the categories. ?
In the advanced footer, you create rows and then blocks in the rows.
Create a row
Go to Customization -> Advanced footer -> Blocks.
Click on Create New button on top right corner of the page. make sure the "Themes" setting is selected to all. when you create the row.
After creating a footer row, now you need to add blocks in this row.
Click on Create block button and add your blocks.
After following this steps, the advanced footer should show on your website.
