Autoblogged problem

Hello!

I found the rss poster I searched longly, AUTOBLOGGED, but the image import is not working.

In the setting page there is a warning over every post:

Unable to retrieve image (400): URLOFTHEIMAGE

If I go to the URL showen in the error message I see the photo. (jpg)

The cache folder has 777, but why it is not working?

Thank you!

Edit:

The diagnostics show me this error:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set in /wp-content/plugins/autoblogged/diag.php on line 464
