Having trouble installing Advanced Guestbook

I am trying to set up admin account on an Advanced Guestbook and I keep getting this error "500 Internal Server Error". My settings on the config.php are correct...at least I think....and I have the right permissions on the files. The tables were created, but the next step was to click here to set up admin account. I can't get beyond that step. If someone could help me, I would be forever in your debt.

Thanks.

That is the error I get when I mess around with the permissions. There has to be something I am overlooking. Please help.

matter of fact....I notice that when I click to create tables and it brings you to the screen saying tables were created successfully which says

your new database: test
your MySQL host: (here's where it's interesting....it uses the database name as the host....even though I have specified what the name of the host is in the config.inc.php.

How can I make this correct. Perhaps this is why I keep getting an error and can't get past that page to setup the guestbook admin.

Thanks for anyone who can help!!!!

just delete all the files from ur server then input your
database name
username
password
on ur pc
then upload it to the server by FTP (ws_ftp) not by the CONTROL PANEL in Poweb
Some problems you might have could be the results of wrong chmod settings.

Here is how I have the chmod setup:

755 rwx/rwx/rx
777 rwx/rwx/rwx
admin 755
doc 755
img 755
lang 755
lib 755
public 777
templates 777
tmp 777

Deleted all the files as you suggested. I'm not sure what you mean about input your *information* but I'm guessing you mean to do it in your config.inc.php. I did that.

I don't use control panel from powweb. I didn't even know they had that. I actually use ws_ftp already. All my permissions are set correctly. I started all over again and when I got the screen saying your tables are created...and then to click here to setup admin, I get this message:

MySQL Error : Connection Error
Error Number: 1045 Access denied for user: '**********@www09.powweb.com' (Using password: NO)

And I still get the guestbook name as the listing for the MySQL host. I don't understand why it doesn't plug in the host name that I gave it in the config.inc.php. This is really making me angry. I greatly appreciate the help "connect" and would be just as grateful for more. Anyone got any ideas. THANKS!!!

I think I figured it out why it wasn't working. I think mysql didn't like a password that started off with a character. As soon as started from scratch and used a different password w/o characters....It came right up. I appreciate everyone's help.
