Entered wrong URL in preference fields

Hello,

The blog is on “www.sneum.dk”

I made the error of entering the variable “?lang=en” in the URL field under preferences, with the result that the site is ow broken and I cannot access the wp-admin (for quite obious but none the less embarrasing reasons).

Now, I was wondering if theres anything I can do if i FTP in or try to access the db directly – what should I change so I can get the value of the field to be just “www.sneum.dk”.

Hope you have the time to answer, thank you for a fantastic piece of digital product,

Frederik
