Fatal error: Call to a member function xpath() on a non-object in /.../inc/inc.ClassSettings.php on line 233

023: echo 'file: inc/inc.ClassSettings.php<br />';
142: function Settings($configFilePath='') { /* {{{ */
151: echo '151: $configFilePath= ', $configFilePath, '<br />';
228: function load($configFilePath) { /* {{{ */
229: if(!empty($configFilePath)) {echo '229: $configFilePath=', $configFilePath, '<br />';}
230: $xml = simplexml_load_string(file_get_contents($configFilePath));
231: if(!empty($xml)) {echo '231: ', $xml, '<br />';} else echo '231: $xml= no value for $xml</br />';

The file is where it's supposed to be:
/conf
settings.xml 8.2KB xml document -rw-r--r--

So it looks to fail at: $xml = simplexml_load_string(file_get_contents($configFilePath));

Does 'echo file_get_contents($configFilePath)' just before the line with simplexml_load_string() return the content of the config file? I still think that the problems lies in reading the config file.
