I looked at the code and can't see anything being blocked in the footer, except when the cookie notice appears.
The theme seems to have 2 footer sections a top & bottom.
The 3 columns widget areas in the top footer section appear to be empty so you will need to go to Appearance > Widgets inside the WordPress admin area
You will then most likely see something like Footer Column 1, Footer Column 2 etc or something similar.
You will need to put widgets in those areas for them to appear.
The bottom footer section is a credit link to the theme author, some themes let you remove that, but as I don't know the theme you will need to go through the settings
Hope that helps
