I've added the WordPress application to my LinkedIn account. Well, I added it a long time ago. And it's been working fine until today when I switched to the Thematic WordPres theme. When switching to Thematic the LinkedIn WordPress app returned the "sorry, we can't find a WordPress blog at this adress" error.
Yes, I've tried the base URL as well as the feed URLs.
In any case, I've switched to another theme so that the LinkedIn app would work. I'm not really sure where to start to debug this as I don't know how WordPress and LinkedIn integrate.
FWIW my blog is andyerickson.org and my LinkedIn profile is www.linkedin.com/in/andyerickson. If you want to see the problem, email me at firstname.lastname@example.org and I'll switch the theme back to Thematic.
