I would also suggest you check those paths - that is a Plesk path that was discontinued several versions back.

Plesk is now 8.1 - that version sounds like 4 or 5!!

If you are still on a really old Plesk - you need to ask your hosting company why. Is it because the server is so old that they can't update (if so then you are suffering) - or is it because they are poor at updating their servers (again you may suffer from old versions of PHP and MySQL)

If not then your paths should look like...

/var/www/vhosts/vhosts/whitneyportalstore.com/cgi-bin/ubb/Members

It is possible that your host has mapped a psa directory to avoid paths from breaking - but as these directories went out of Plesk 2 or 3 years ago (or more) then I would have thought not.

Just a few ideas for you.

The members directory problem was solved by the host site administrator. He wrote this to me:
