Glad it worked out for you! Almost lost my mind trying to resolve this issue. Maybe Woo could add this to their list of things to check when troubleshooting the PayPal checkout within their documentation. I had followed all of their suggestions within that document and this was obviously what was causing the issue. Anyway, best of luck in the future!

Okay, turns out that myself and Woo support can’t figure out where this script is located, but they did identify it as coming from Attracta, which I know I may have picked up through their SEO option in CPanel via HostGator. Sorry that’s not much help, but hopefully if it prevents people from using the SEO setup and this happening in the future then it’s worth it.

Just spoke to one of the Woo guys and apparently I’ve got a bunch of extra Javascript running I don’t need.

See code here: https://cld.wthms.co/Srrh

Told me to remove it and see if that changes anything. Will report back if it works.
What I did find that bypassed the error for some reason was using a paid e-commerce PayPal system that requires an API username and Signature – for example Marketpress ($20 premium.wpmudev.org/project/e-commerce/)or the PayPal Express Checkout through WooCommerce (which alas costs $50). Funnily enough (or not as the case may be) paid for the Woo plugin and not ten minutes later got the suggestion to remove the code from Woo. Maybe they saw they’d just made $50 and took pity on me ??
Will report back if this fixes the issue, hope this gives someone a slightly more optimistic outlook – was really starting to lose my mind over this.

Having the same issue in Woocommerce with the Canvas theme. Strangely enough transactions seem to work when accessed through Paypals own Sandbox test site. Did you find a resolution to your problem? WooThemes support is painfully slow to respond.
Similar issue mentioned by dshawotet on page one of this thread and Thomas Morley on the third page. Glad to see I’m not the only one having an issue with this. Anybody have any suggestions?
