Internet Explorer Doesn't like extra commas in javascript. It wants to find the next variable that doesn't exist. I was able to get the plugin working in IE7 by removing the extra variables as follows…

Line 449 – You'll find this….

///////

foreach ( $this->_settings['featured-content-showcase'] as $setting => $value ) {

///////

We need to find the last element in an array so we know where to remove the extra comma…
So I'm creating a variable that finds the end of the array.
///////

$last_key = end(array_keys($this->_settings['featured-content-showcase']));
foreach ( $this->_settings['featured-content-showcase'] as $setting => $value ) {

///////

Line 459 (or about there) – Find this….

///////

echo "{$setting}:    {$value},\r\n";

///////

Replace with this….

///////

if($last_key == $setting) {
echo "{$setting}:    {$value}\r\n";
} else {
echo "{$setting}:    {$value},\r\n";
}

///////

Then we need to remove the last comma in the default settings as well….

Line 594 – (or close, we've pushed everything down a bit.)
Find this….

///////

'panel_scale'            => 'nocrop',

///////

And remove the end comma….

///////

'panel_scale'            => 'nocrop'

///////

Then save the file.

Google and Microsoft have officially stopped supporting IE6…. and so should EVERYONE. I did not test this in IE6. I'm telling all my clients, "I no longer do work for IE6" But I did test this in IE7 and it works. Be sure to emtpy cache and reload the page for testing.
Hope this helps out!

I'm not sure how to include

$last_key = end(array_keys($this->_settings['featured-content-showcase']));
foreach ( $this->_settings['featured-content-showcase'] as $setting => $value ) {

in featured_content_showcase.php. I gather it needs to be a part of the same php 'string' (excuse me if I'm using the incorrect term) as

foreach ( $this->_settings['featured-content-showcase'] as $setting => $value ) {

but I don't know how far down to insert it. Cou you give me an example of your code?

Thanks,

Iain
