Thread:Project:Support desk/Using Maintenence Extension to generate sitemap/reply (3)

Ok, telling us your limitations about not having shell access in the first place would help.

Try creating a new PHP file that would execute the command to generate the sitemap, usinh the exec function. If that fails it would be worth reading this, and search on the internet about running shell or PHP-CLI scripts on your shared hosting: you'll probably find useful responses about your problem.
