You need to change this:
wp_register_script(‘wpb-js’, WP_PLUGIN_URL.’/wp-blocks/js/wp-blocks.js’);

To this:
wp_register_script(‘wpb-js’, WP_PLUGIN_URL.’/wp-blocks/js/wp-blocks.js’,array(),false,true);

Inside wp-blocks.php

It fixed it for me.

Congratulations slinkyap 😉
I had some problems with the wp-e-commerce.js file as well, but they were caused by me wanting to use the latest jquery version in the theme. I had to rely on using 1.4 for it to remain functional.

Hi slinkyap,

As far as I can tell, there’s nothing wrong with the multi-currency plug-in, but instead with some of the javascript you use on your website.

With javascript disabled, the page loads just fine with the proper currency:

When enabling javascript, a few seconds after the page loads the currency switches for no apparent reason back to Aud.

Good luck with debugging it, at least you know now where to look 😉

I’ve created a short 7-lines filter doing just that (shorter and easier to understand imho):

I couldn’t detect properly the ‘primary’ currency symbol, so my fix will probably tackle the “$” problem only.
Not an expert here, so suggestions are welcomed.

Posted the entire updated wpsc-currency-changer.php (version 0.1) file here:
http://multi-currency-magic.pastebin.com/MktKvAcN

In case the plug-in gets updated, I pasted below the changes I made to the file:

The important lines follow:
Updated this function:

function wpsc_add_currency_code($total){
	global $wpsc_cart;
//	exit($wpsc_cart->selected_currency_code);
	if ($wpsc_cart->selected_currency_code != 'USD') {
		$total = str_replace('$','',$total);
		$total = $wpsc_cart->selected_currency_code.' '.$total;
	}
//	exit($total);
	return $total;
}

function wpsc_add_currency_code_to_price($productprice){
	global $wpsc_cart;
	if ($wpsc_cart->selected_currency_code != 'USD') {
		$productprice = str_replace('$','',$productprice);
		$productprice = $wpsc_cart->selected_currency_code.' '.$productprice;
	}
	return $productprice;
}

And at the end of the file (before ?>) the following line is added:
add_filter('wpsc_price_display_changer_to_price', 'wpsc_add_currency_code_to_price');

The wpsc_add_currency_code function updates the cart area (removes the $ sign, and appends the new currency symbol before the price if the currently chosen option is not USA).

The wpsc_add_currency_code_to_price function updates the prices in-page (just like on the cart). Unfortunately there isn’t a way to update the product price symbol (since there’s no filter available).. so a change to the wp-ecommerce files need to be made.

The following file needs to be changed:
/wp-e-commerce/wpsc-includes/wpsc_query.php

Inside the wpsc_the_product_price function I added the $output = apply_filters(‘wpsc_price_display_changer_to_price’, $output); line near the end:

function wpsc_the_product_price($no_decimals = false) {
	global $wpsc_query;
	$price = calculate_product_price($wpsc_query->product['id'], $wpsc_query->first_variations);
	if(($wpsc_query->product['special_price'] > 0) && (($wpsc_query->product['price'] - $wpsc_query->product['special_price'] ) >= 0) && ($variations_output[1] === null)) {
		$output = nzshpcrt_currency_display($price, $wpsc_query->product['notax'],true, $wpsc_query->product['id']);
	} else {
		$output = nzshpcrt_currency_display($price, $wpsc_query->product['notax'], true);
	}
	if($no_decimals == true) {
		$output = array_shift(explode(".", $output));
	}
//	echo 'NO DECIMALS VALUE:'.$no_decimals;
	//echo "<pre>".print_r($wpsc_query->product,true)."</pre>";
	$output = apply_filters('wpsc_price_display_changer_to_price', $output);
	return $output;
}

The same error happened to me, but in a different place
* after registering a new user
* after posting a new comment
(on server with PHP 4.4.7)

I tried it with all the plugins disabled and with the default theme.
Same error:
Warning: call_user_func_array() [function.call-user-func-array]: First argumented is expected to be a valid callback, ‘sanitize_url’ was given in /home/pyaorgco/public_html/wp-includes/plugin.php on line 59

Warning: Cannot modify header information – headers already sent by (output started at /home/../public_html/wp-includes/plugin.php:59) in /home/../public_html/wp-includes/pluggable.php on line 391

I installed the same wordpress on another server (with PHP 5) and the error disappears. Can this work on PHP4 too ?
