Hi,
we add new footer as your wish :)
So, you just need to add new content in your Widgets and add some nav pages to footer menu. All content we add there is just for testing.
If you want to change icons in Third column, you can do that in your contact-info.php file
(you can find it here \wp-content\themes\revelance\inc\widgets\contact-info.php)
and on file 37 to 42 you can set your new icons names.
Also, there is an issue with Purge Varnish plugin. This is third party plugin and when its activated, css in your footer won’t work. For third party plugin we do not offer support so we deactivate this plugin.
Kind regards
