When I try to refresh my blog I get the message : "Can’t get recent posts for [my blog] because the server reported an error: Invalid blog id specified." My blog is a blogger blogspot blog. My blog's settings are autodetected. Thank you for your help.
@ndova: Please let me know a bit more about what's going on for you. Is it possible the auto-detection didn't work completely? Did MarsEdit complain about anything when you try to set up the blog in it?
