Sitemap Module daily task breaks

Just tried to get the sitemap to work, the cron job fails - because of the following message:

Parse error: syntax error, unexpected T_START_HEREDOC in ****/application/modules/sitemap/models/Sitemap.php on line 35

Tried to fix that somehow, but then getting:

Fatal error: Uncaught exception 'Zend_Http_Exception' with message 'Cookies must have a domain' in ****/library/Zend/Http/Cookie.php:124 Stack trace: #0 ****/library/Zend/Http/Cookie.php(359): Zend_Http_Cookie->__construct('PHPSESSID', 'b088c1f05a6dc75...', '', NULL, '/', false) #1 ****/application/modules/sitemap/models/Sitemap.php(190): Zend_Http_Cookie::fromString('PHPSESSID=b088c...') #2 ****/application/modules/sitemap/models/Sitemap.php(75): Sitemap_Model_Sitemap->_extractLinksFromUrl('http://www.shir...') #3 ****/application/modules/sitemap/handlers/Events.php(45): Sitemap_Model_Sitemap->generate('http://www.shir...') #4 ****/library/Singular/Event/Dispatcher.php(48): Sitemap_Handler_Events->onCronDaily(NULL) #5 ****/library/Singular/Event.php(89): Singular_Event_Dispatcher->dispatchEvent(Array, Array) #6 /us in ****/library/Zend/Http/Cookie.php on line 124

Because the Zend_Http_Cookie::fromString fails because of missing domain name for the cookie (maybe an error resulting of my "patch").
