After fighting more hours with function that I used to remove “powered by..” line, I was able to figure this one out. This is resolved. In case someone wants solution that I used, below is what i added to functions.php file.
add_action( 'init', 'custom_remove_footer_credit', 10 );
function custom_remove_footer_credit () {
remove_action( 'storefront_footer', 'storefront_credit', 20 );
add_action( 'storefront_footer', 'custom_storefront_credit', 20 );
add_action( 'storefront_footer', 'custom_footer_accepted_payments', 20 );
add_action( 'storefront_footer', 'custom_footer_securedby_seals', 20 );
}
function custom_storefront_credit() {
?>
<div class="site-info" style="float:left">
<!--- HTML/php Code to modify credit line---!>
</div><!-- .site-info -->
<?php
}
function custom_footer_accepted_payments() {
?>
<div class="site-info" style="float:right">
<!--- HTML Code to add accepted payment---!>
</div>
<?php
}
function custom_footer_securedby_seals() {
?>
<div class="site-info" style="float:right">
<!--- HTML Code to add ssl seal ---!>
</div>
<?php
}
