 +
 +This error appears in the PHP log:
 +
 +<code>
 +PHP Warning:  curl_setopt() [<a href='function.curl-setopt'>function.curl-setopt</a>]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /var/foo/bar.php on line 123
 +</code>
 +
 +Updating open_basedir to include the directory won't work, because the curl option ''CURLOPT_FOLLOWLOCATION'' is disabled by PHP when ''open_basedir'' is set.
 +
 +The purpose for this not working is that curl will follow a result with a header pointing to another location, which creates the option of directory traversal outside of the limited basedir.
 +
 +This change was introduced in PHP 4.4.4.
