Okay, I’m beginning to think that too. Im going to go ahead and mark this resolved because I dont think its being caused by your plugin(its weird that the plugin is on the error though). Anyway, your plugin works great, keep up the good work!

Yes the link will take you to paypal, but a email keeps being sent

Please check your server that handles PayPal Instant Payment Notification (IPN) messages. Messages sent to the following URL(s) are not being received:

https://www.hopeforthree.org/?simple_cart_ipn=1

If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information.

Once you or your service provider fix this problem, you or your service provider can resend the failed messages from the IPN History page. If this problem continues, PayPal may disable the IPN feature for your account.

Thank you for your prompt attention to this issue.

Thanks,
PayPal

Error Message

Fatal Error: Call to undefined function wpc_handle_paypal_ipn() in /var/www/vhosts/hopeforthree.org/httpdocs/wp-content/plugins/wordpress-simple-paypal-shopping-cart/wp_shopping_cart_misc_functions.php on line 19
Description

The WP Simple Paypal Shopping cart plugin code created an error that caused PHP execution to fail.

The code tried to run a function that doesn’t exist (wpc_handle_paypal_ipn()). This type of error is typically caused by a simple typo (is_hom() rather than is_home()), by calling a function provided by a plugin when that plugin is not activated, by calling a function before it is ready (such as calling a function before the code that creates it has run), or by using a function that no longer exists (the function may have been removed from WordPress core or the plugin/theme that previously supplied it).

Solutions

Invalid code modifications can cause this problem. If you have made any modifications to the plugin, remove them and try to load the site again.
It is possible that this plugin’s code is out of date and that an upgrade is available. Check with the plugin’s author to see if an upgrade is available.
There may be a conflict with another plugin running on the site. Try upgrading the other plugins on the site. A plugin conflict can be ruled out by deactivating all the other active plugins on the site and checking to see if the error still occurs.
The WP Simple Paypal Shopping cart plugin may not have been fully uploaded. Uploading the plugin again could fix the issue. Important: If you do this, you will lose any modifications made to the plugin.

The cart works fine, thanks. But that error keeps being emailed.

Yea, I updated to 4.1.4. Is the ipn listener https://www.hopeforthree.org/?simple_cart_ipn=1 ?

Sorry about my absence.
Is the ipn listener https://www.hopeforthree.org/?simple_cart_ipn=1 ?
Im getting an error, if you stop the page from redirecting to paypal and look at the details you’ll see whats going on.
Ive enabled and disabled IPN on paypal with the notification url set to https://www.hopeforthree.org and https://www.hopeforthree.org/?simple_cart_ipn=1
Neither setting made a difference.

I tried the PayPal’s IPN simulator but its showing “We could not send an IPN due to an http error.”

Okay. So IPN wasnt enabled on the paypal account. I have sinced enabled it. Now Im seeing this

What sticks out is this line
The code tried to run a function that doesn't exist (wpc_handle_paypal_ipn()). This type of error is typically caused by a simple typo (is_hom() rather than is_home()), by calling a function provided by a plugin when that plugin is not activated, by calling a function before it is ready (such as calling a function before the code that creates it has run), or by using a function that no longer exists (the function may have been removed from WordPress core or the plugin/theme that previously supplied it).

Looking at the code should “wpc_handle_paypal_ipn()” be “wpc_handle_paypal_ipn())” ???

function wp_cart_init_handler()
{
    $orders_menu_permission = apply_filters('wspsc_orders_menu_permission', 'manage_options');
    //Add any common init hook handing code
    if( is_admin() && current_user_can($orders_menu_permission)) //Init hook handing code for wp-admin
    {
        wpspc_create_orders_page();
    }
    else//Init hook handing code for front end
    {
        wpspc_cart_actions_handler();
        add_filter('ngg_render_template','wp_cart_ngg_template_handler',10,2);
        if(isset($_REQUEST['simple_cart_ipn']))
        {
            include_once('paypal.php');
            wpc_handle_paypal_ipn();
            exit;
        }
    }
}

I just installed it from the www.ads-software.com repo.

Here is the function the error is referring to:

// Start of IPN handling (script execution)
function wpc_handle_paypal_ipn()
{
    $debug_log = "ipn_handle_debug.log"; // Debug log file name
    $ipn_handler_instance = new paypal_ipn_handler();

    $debug_enabled = false;
    $debug = get_option('wp_shopping_cart_enable_debug');
    if ($debug){
        $debug_enabled = true;
    }

    if ($debug_enabled)
    {
        echo 'Debug is enabled. Check the '.$debug_log.' file for debug output.';
        $ipn_handler_instance->ipn_log = true;
        //$ipn_handler_instance->ipn_log_file = realpath(dirname(__FILE__)).'/'.$debug_log;
    }
    $sandbox = get_option('wp_shopping_cart_enable_sandbox');
    if ($sandbox) // Enable sandbox testing
    {
        $ipn_handler_instance->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
        $ipn_handler_instance->sandbox_mode = true;
    }
    $ipn_handler_instance->debug_log('Paypal Class Initiated by '.$_SERVER['REMOTE_ADDR'],true);
    // Validate the IPN
    if ($ipn_handler_instance->validate_ipn())
    {
        $ipn_handler_instance->debug_log('Creating product Information to send.',true);
        if(!$ipn_handler_instance->validate_and_dispatch_product())
        {
            $ipn_handler_instance->debug_log('IPN product validation failed.',false);
        }
    }
    $ipn_handler_instance->debug_log('Paypal class finished.',true,true);
}

Do you see anything wrong??

There isnt a cart page. The main shop page is https://www.hopeforthree.org/shop43

Thanks for the reply

it was the actual plugin file,in my case it was in
jck_woothumbs/jck_woothumbs.php

ok, found this ‘<?php include(‘images/social.png’); ?>’ at the end of the php script. easy enough to find, deleted it and everything seems fine for the time being at least…

now im not able to get to wp-admin or login all that i see is ‘Warning: include(): Failed opening ‘images/social.png’ for inclusion (include_path=’.:/opt/php54/lib/php’) ‘ im checking the file using ftp to see whats going on..
anyone know what the /opt/php54/lib/php is?

I got a email about my wp-config being modified, i searched for ‘%wp_data_newa%’ in mysql and sure enough i found an entry, i did another search for ‘social.png’ and there was another one in other plugin! deleted both, hopefully its gone for good.

found it searching for social.png and removed the sql entry. and changed my Authentication Unique Keys and Salts. any other suggestions?
