WordPress incorrect URL

Hi all,

Managed to break my WordPress install, was screwing around with the ‘extension’* part (the option for the part after the URL) in admin panel. Now I cant access my blog at all, whenever I go to my site it attempts to connect to: “/wordpress/wordpress” whereas the actual site is just in the -single-subdirectory /wordpress

I am not sure which part of the database holds this ‘extension’*
I only have access to the CLI so using other tools is out of the question.

Any ideas?

Regards,

Mike.
