I downloaded and installed, via the Joomla extension manager, the package for Joomla Update. It gave me the finish statement that it was installed, so I clicked on components, update manager and received this:

Fatal error: Call to undefined function: stream_get_wrappers() in /usr/local/etc/httpd/htdocs/wrvrlives/administrator/components/com_jupdateman/views/jupdateman/view.html.php on line 44


Not sure what to do.
