Trouble with installing WordPressMU

For those unfamiliar:

I did everything correctly through my FTP client, went to the site and put the database etc etc in and it said complete. I go to my email to log in and I get this message -

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Anyone know the deal with that? :S

Well, it looks like you have a bit of a mess going on. :wink: It’s really hard to tell where you might have gone wrong without access to your error logs (that’s where you will get your best clue(s) as to the nature of the problem), and a generic “Internal Server Error” doesn’t really tell you much.

Also, you wrote:

This is strange, as I have no idea why you would go to your “email” to login :open_mouth: , and have no idea what you are really trying to say here.

From looking at your site, it looks as though you have attempted to install your own PHP, and have that pretty well “borked” - shows a strange configuration (and I’m not sure why you would even need that. You can run WordPressMU with the installed DH PHP (no need to use your own).

Finally, browsing to your site at and entering the WPMU directory produces additional error messages that indicate either the software is not installed or your paths are hopelessly borked.

You need to “undo” whatever you did (except the apparently functioning Joomla! installation), and start over. WordPressMU is notoriously “difficult” for beginners to install, and you cannot use the wildcard dns functionality to house the users’ blogs without special request to DH support to have this enabled for your domain. This is not suitable for “beginners” :wink: .

At any rate, if you intend to install WordPress MU, I suggest you undo your earlier attempt, and carefully follow this DH Wiki article on installing WPMU. Note also the link at the bottom of the page to a different tutorial on installing WPMU on Dreamhost.

You might also consider an alternative, which is much more easily installable on DH, which is Lyceum, a multi-user/multi-blog fork of original WordPress code. Installing Lyceum should take about 10 minutes if you read the documentation carefully.


Thanks for the reply. I’ve come pretty close to getting it done properly(WPMU that is). I tried Lyceum but couldn’t come to like it as much as WPMU. Now I’ve gotten to the installation part but when I finish entering my database information I get the following:

WordPress database error: [Duplicate entry ‘1’ for key 1]
INSERT INTO wp_sitecategories ( cat_ID, cat_name, category_nicename, last_updated ) VALUES (1, ‘Uncategorized’, ‘uncategorized’, NOW())

WordPress database error: [Duplicate entry ‘2’ for key 1]
INSERT INTO wp_sitecategories ( cat_ID, cat_name, category_nicename, last_updated ) VALUES (2, ‘Blogroll’, ‘blogroll’, NOW())

? lol

It looks like the “ghosts of past installation attempts” are “haunting” you. If you are sure you now have the installation “right”, I’d suggest going into your database via PhpMyAdmin and deleting all the existing tables that are related to WPMU, and installing again.

Your error messages appear to be saying that you you are trying to insert data that is already in the database - you can resolve that by starting over with the Database tables, as well as the script code. :wink:
