After some heroic investigation on our engineering side, we found what might be the cause.
It turns out, our fetcher does some canonization of URLS, transforming http://www.raptorsrepublic.com/2013/10/09/practice-recap-valanciunas-english-cumulative-talent-ross-laid-back/ into http://www.raptorsrepublic.com/2013/10/09/practice-recap-valanciunas-english-cumulative-talent-ross-laid-back (Note the missing trailing slash on the second one.)
When I type the above no-trailing-slash URL in a browser, I get an empty page. Hence, the “Invalid Card type”.
I also noticed that you’re hosting a WordPress site. When I look at other Wordpress sites, I see it handle the no-trailing-slash gracefully by redirecting to the trailing slash version. Here are some examples:
Again, all redirect to the same URL with a trailing slash.
I can ask the engineers to take a look, but I know that may take some time. So I wonder, do you happen to know why your WordPress site is different than other ones, and is there something different in the configuration we could change to have it gracefully redirect like other wordpress sites?
Know it’s maybe not the most helpful, but I want to get you up and running soon – know you’ve been patient.
Thanks a ton!
