on localhost getting error.

To clarify, it works fine on your live site, but on your dev site, you get the scabn_paypal not found error? Can you tell me what is different between the two sites? Web server, php version, WP version, multi-site WP vs single site, etc?

I waited to reply so I could test the issue on a new install. and the same issue duplicated itself. The SCABN plugin seems to be working on the live site, but creating the error below on the localhost site.

WAMPServer:2.2, Apache Version:2.2.21, PHP Version:5.3.8, MySQL Version:5.5.16, WordPress:3.5.1 (single site), Responsive Theme:1.9.1 [not a child](first installed duplicated error and then updated to 1.9.3 and error still present). SCABN is only plugin.

The error below seems to remove the WordPress Admin bar and widget sidebar on the Checkout page only.

I’m still not clear on what is different between the (working) live site and your non-working local site.

Live working site: Apache Version:2.2.22, PHP Version 5.3.21, MySQL version: host interface reports 5.0 – but phpinfo reports Client API version 5.5.19, WordPress:3.5.1 (single site), Responsive Theme:1.9.1; and lots of plugins.

more info, live site appears to run APC-Alternative PHP Cache : apc Version 3.1.13

Ok, I’ve since had a few other people have this problem. The issue is classes/paypal.php start with

<?

instead of

<?php

Both work on many server configurations, but not all. I’ve fixed this in svn, but until I push a new version, just edit classes/paypal.php (and google.php) and have it begin with <?php
