My b2evolution Version: 1.10.x

I've read through all of the flickr threads I can find on the boards and I'm still stuck. I just upgraded to 1.10.2. I have my site set up in flickr as a MetaWeblogAPI, and I added a default category to my _advanced.php config file. When I do a test post within flickr, it tells me the post failed, but in my posts list I see a blank post in the default category. I can't figure out why it would be making a post but ignoring the picture information, or why flickr seems to think that the posts are failing. I even tried paring the flickr layout down to the bare bones:

<a href="{photo_url}"><img src="{photo_src_m}" /></a>
<br />
{description}

Any suggestions? My site is here:
