Fatal error: Maximum execution time of 10 seconds exceeded in /virtual/server_address/oc-includes/osclass/classes/database/DBCommandClass.php on line 1626
Everytime, when I click on Sitemap generator i get whis notification, but everytime on line xxx is different.
I have no Idea what's going on. Can anyone help?
