I have installed the iCustomFooter and set all the options as the requirment.

But it doesn't display on the footer.

What are the steps to display iCustomFooter on footer in opencart? 

Hello @julia,

If you are using OpenCart 2.x, please make sure that the modifications are refreshed (From Admin Panel > Extensions > Modifications > Refresh) after you have installed the module. If they are, but the iCustomFooter still doesn't show, the reason might be a custom theme that you are using. If so, please raise this issue in our ticket support system here: https://isenselabs.com/tickets/open
