unserialize issue, suggest to use maybe_unserialize function

Hi there,

Thank you for the plugin. I’m having an issue with “Warning: unserialize() expects parameter 1 to be string, array given” when using along with the docket cache plugin.

I would like to suggest changing the “unserialize” function to “maybe_unserialize” to solve this issue.

For example,

File: ultimate_social_media_icons.php
Line: 114

Before:

function sfsi_error_reporting()
{
    $option5 = unserialize(get_option('sfsi_section5_options', false));
    if (
        isset($option5['sfsi_icons_suppress_errors'])
        && !empty($option5['sfsi_icons_suppress_errors'])
        && "yes" == $option5['sfsi_icons_suppress_errors']
    ) {
       	error_reporting(0);
    }
}

After:

function sfsi_error_reporting()
{
    $option5 = maybe_unserialize(get_option('sfsi_section5_options', false));
    if (
        isset($option5['sfsi_icons_suppress_errors'])
        && !empty($option5['sfsi_icons_suppress_errors'])
        && "yes" == $option5['sfsi_icons_suppress_errors']
    ) {
       	error_reporting(0);
    }
}

Thanks.
