... also, I found that the only item in the "Share this:" that was causing me PHP errors was the Twitter one. It was the line that reads ...

$turl = getTinyUrl(get_permalink($post->ID));

So I just commented out that share item. Facebook, Digg & Email links work fine. Error is now gone.

Thanks for sharing the info!

I just wanted to add that my host does not allow you to access the main php.ini file, but you can drop in your own php.ini file with the modified value(s) and it works like a charm. Just thought I would share this tidbit of information incase someone is having the same trouble that I ran across.

Also, my host is 1and1... not sure if other hosts handle php.ini files the same way, but I figured it was worth the post.

If you are getting Warning Messages like this one:

"Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration..."

This means that your server configuration is blocking external file access.

Solution:
allow_url_fopen should be ON in PHP configuration (php.ini). You may not have access to edit this file and it could also be that your hosting company has restricted changing the allow_url_fopen value. In this case, you should refer to them and ask them to set the value of allow_url_fopen to ON.
