Javascript errors

I am trying to setup PayPal Payments Pro on zebraprintersonline.com.au but am having a few issues with JavaScript errors. The shopping cart when it loads throws the following errors in the JavaScript Console:

Resource interpreted as Script but transferred with MIME type text/html: "http://zebraprintersonline.com.au/products/shopping-cart/WA_eCart/js/eC_Display.js". (index):288
Uncaught SyntaxError: Unexpected token < eC_Display.js:1

When I go to the checkout page I get these errors in the console:

Resource interpreted as Script but transferred with MIME type text/html: "http://zebraprintersonline.com.au/webassist/ecart/checkout/js/paymentoptions.js". checkout.php:1211
Uncaught SyntaxError: Unexpected token < paymentoptions.js:1
Uncaught TypeError: undefined is not a function common.js:3(anonymous function) common.js:3n jquery-1.7.1.min.js: 2o.fireWith jquery-1.7.1.min.js:2e.extend.ready jquery-1.7.1.min.js:2c.addEventListener.B jquery-1.7.1.min.js:2

Clicking on the Payment Options radio buttons adds the following error to the mix:

Uncaught ReferenceError: wa_paymentChanged is not defined checkout.php:247 onclick

I'll need to troubleshoot directly, see the private message section.

See PM

you have conflicting versions of jquery on the pages.

<script src="/js/bootstrap/jquery.js"></script>
<script src="/js/jquery-ui-1.8.16.custom.min.js"></script>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js"></script>


The query scripts can only be added once to the page.

I've removed the duplicate jquery includes but I still get javascript errors.

Something in your htaccess file is preventing access to the cart scripts

try to go to:
http://zebraprintersonline.com.au/webassist/ecart/checkout/js/paymentoptions.js

and it opens the confirm page.

if i rename the htaccess file then it works correctly.

With the htaccess file renamed, the cart and the confirm page do not show the errors

Thanks Jason the issue was with two rewrite rules after I commented them out and changed the links sitewide it fixed the issues:

# RewriteRule products/shopping-cart/ cart.php
# RewriteRule checkout/ checkout.php

you're welcome.
