global config not showing up

[lumpkan1]

when i log into the site i get the following error message:
Fatal error: Cannot make non static method JCacheStorage::test() static in class JCacheStorageCachelite in /home/wheels/public_html/libraries/joomla/cache/storage/cachelite.php on line 334


This happens when i click on global config.
here is the code:
jimport('joomla.filesystem.folder');

if (trim($group) == '')
{
$clmode = 'notgroup';
}

if ($mode == null)
{
$clmode = 'group';
}

switch ($mode)
{
case 'notgroup':
$clmode = 'notingroup';
$success = self::$CacheLiteInstance->clean($group, $clmode);
break;

case 'group':
if (is_dir($this->_root . '/' . $group))
{
$clmode = $group;
self::$CacheLiteInstance->setOption('cacheDir', $this->_root . '/' . $group . '/');
$success = self::$CacheLiteInstance->clean($group, $clmode);
JFolder::delete($this->_root . '/' . $group);
}
else
{
$success = true;
}

break;

}
else
{
$success = true;
}

break;

Hi lumpkan1,

This is a joomla core related problem and maybe your php version also, could you try to install a fresh joomla to see if this occurring ? what is your php version ?
