Recommended Reading needs to load a foreign XML feed from Google. Your host has turned off support for "fopen" and cURL - the two most widely supported mechanisms for loading foreign information like your shared feed. Please contact your host and ask them to enable the cURL PHP module or add "allow_url_fopen" in your PHP configuration.

Help support continued development of Recommended Reading and other plugins.
The best thing you can do is refer someone looking for web development or strategy work to our company.
Short of that, here are other ways you can help:
| Google Reader ID [?] | |
|---|---|
| Look up my Google Reader ID | |
| Google Username | |
| Google Password | |
| Your server does not have cURL enabled. cURL is a widely supported PHP module used to load and process external web pages behind the scenes. Unfortunately, cURL support is needed to dynamically look up your ID. You may still manually find and enter your ID. Click the question mark link above for instructions. | |
You can display your Google Reader shared items on a dedicated page or post by simply typing [recreading] into the content (WordPress calls this "shortcode"). An optional attribute, 'items', can be set to the number of items you want to display; for example, [recreading items=5] to show 5 shared items.
The shortcode will use the settings above, but also has a few additional settings you can control.
