From my hosting company's support site. Very useful...
1) Install Dolphin into a directory
2) Move
all files from the directory you installed Dolphin into to the root
directory (you can do this using the file manager or a FTP client)
3) Edit the file inc/header.php
4) Inside header.php, alter the variables: $site['url'] (to include just your URL and not the directory) as well as $dir['root'] (to include everything but the directory name that you installed to)
5) Edit the file ray/modules/global/inc/header.inc.php
6) Alter the line which starts with include("/home/..... and ends with ...header.inc.php"); by removing the directory name you installed dolphin into.
Also,
dolphin sets up some cron jobs for notifications. Inside your control
panel under the icon "Cron Jobs". You should see 3 cron jobs listed.
All of these cron job entries have the directory you installed dolphin
into in them. Please remove the directory name from the line.
Furthermore, each file (periodic/cmd.php, periodic/cupid.php,
periodic/notify.php) has a line at the top that includes the directory
in it as well (as in step 6).
You are done. Now visit your main
URL and you should see Dolphin displaying without any errors. If you
are not sure how to carry out the steps above, please contact support.
