Royal Mail Click and Drop – 403 error

[Alex]

I’m trying to integrate a postal service (Royal Mail, Click and Drop) with Woocommerce. Clicking the link RM provide to do this I get an error page:

xxxxxxx.com 403 Forbidden Error Page

If you arrived here due to a search or clicking on a link click your Browser’s back button to return to the previous page. Thank you.

IP Address: xx.xx.xxx.xx

Checking the BPS logs, the integration is being blocked by BPS (see below). What should I do about this? Is there a way to allow it through? I’ve tried disabling BPS temporarily, but that doesn’t solve it, I suspect because it doesn’t remove the .htaccess and its rules.

Thank you ! That works perfectly.

[Dead Dred]

Just a heads up this also worked for ClickShip.

[AITpro Admin]

Yep, was just about to respond to your forum topic post on the wordpress.org site.  The Request simulates an RFI hacking attempt.  Thanks for confirming that worked.
