As of today, I'm experiencing problems in retrieving my Delicious feed and publish a few items of this feed on my blog hosted on Aruba.
The problem is present only with the feed from Delicious and only on blogs hosted on Aruba (an Italian hosting provider). I tried my code on 4 different domains (hosted on Aruba) and all have this problem. Other blogs, hosted by different providers, do not have any issue in fetching a Delicious feed. Also my LAMP server on localhost fetches any feed correctly.
On Aruba, I tried to fetch a feed from Google Reader and other services with success. Only Delicious seems to be "un-fetchable".
The message I receive is:
Fatal error: Call to undefined method WP_Error::get_item_quantity() in path/to/script/delicious.php on line 16
The code I use is here: http://aldolat.pastebin.com/m21af4a8d (valid for a month).
The origin of the problem seems to be my hosting provider. Can you tell me if it may be possible and which configuration may be the reason for this problem?
