Wrong server file path - how do I change
 

I am changing server and although a fresh install of VB on the new server, and a database import works well, I get some base_dir errors when uploading attachments.

I have seen other posts about this and will follow up suggestions with my host.

However, I notice the error message specifies it is trying to access the wrong server file path. It is the file path used on the OLD forum, not the new forum and server!

I guess the file path is set up in the config somewhere and was imported along with the database from the old forum (I did a fresh install of the actual files, and the server path in config.php is left blank, '', as recommended).

Any ideas where I can change this please? I cannot see any options in the AdminCP where the server file path is specified.
