#75 undefined function com_panel()

[Anonymous]

When I try to log in to the control panel to update our website (http://www.civitasnyc.org/site/index.php?command=panel), I get this error:

Fatal error: Call to undefined function com_panel() in /home/civitas/public_html/site/lucid_phplib/panelLibrary.php on line 11

and I have no idea what to do about it.
