Custom icons broken

Hey, I have this installed on a website with custom icons and there are these problems:
1. The links are not working on frontend (widget)
2. The links are saved but not displayed after refresh in admin panel

I fixed them very easy with one small adjustment:
Your original code has something missing in this part of the code

    /*
     * Escape custom icons url
     */
    if(
        isset($_POST["sfsi_custom_links"]) &&
        !empty($_POST["sfsi_custom_links"])
    )
    {
        $esacpedUrls = array();
        $sfsi_customIconsUrl = $_POST["sfsi_custom_links"];
        foreach($sfsi_customIconsUrl as $sfsi_customIconUrl)
        {
            $esacpedUrls[] = esc_url($sfsi_customIconUrl);
        }
    }

The $esacpedUrls array is saving the links, but when you return them you return them with numeric IDs (in my case I had 3,4,5), but this variable saves them with the IDs 0,1,2. All you need is one small change to save the IDs you got from JS to this:

        foreach($sfsi_customIconsUrl as $key => $sfsi_customIconUrl)
        {
            $esacpedUrls[$key] = esc_url($sfsi_customIconUrl);
        }

I changed mine, but there might be some other people with this issue.
Thanks!
