But in https://

He is getting this error
Warning: require_once(Zend/Session/Namespace.php) [function.require-once]:
failed to open stream: No such file or directory in
/home/.sites/143/site2/web/classes/dwrobot.class.php on line 4

Fatal error: require_once() [function.require]: Failed opening required

mework-1.11.10/library/') in
/home/.sites/143/site2/web/classes/dwrobot.class.php on line 4
