Run this SQL query
update prefixconfig set conf_value="http://www.mydomain.com/foldername" where conf_name="o_base_url"
where prefix is your database prefix and http://www.mydomain.com/foldername is the proper path to the folder
Then, delete the .php files in the cache directory in the forum directory
Can you say all that again but then in English? Haha XD
SQL query?..........................?

And what exactly should I do? In easy words please
Sorry for my small knowlegde about English-Computer-Language
