There’s a real quick fix for those people who are having issues with running both the magpie plugin and the linklist module on the same page. You might receiving this error:

Fatal error: Cannot redeclare class snoopy in /home/andru/public_html/sistem/plugins/pi.magpie.php on line 1798

Please redownload the linklist module from the downloads area and replace the mod.linklist.php and all should be well!
