Here are the steps I have taken to install Wordpress Mu. I will choose the directories option as I have a basic shared account plan and choosing subdomains can be problematic with that plan.

I created subdomain blogs.mydomain.com and uploaded all of the mu files to that domain. I go to blogs.mydomain.com/index.php and enter the correct names of my new database and user as well as password. I leave localhost written for the localhost.

I press submit and get a message saying something like "cannot access database".

So, I read the documentation and learn about chmodding the public_html and wp-content directories to 777. I press submit again and get a 500 error.

I chmod my blogs directory to 777 and still get the 500 error.

When I chmod everything back to 755, I get my cannot access database message again.

After running a search for the problem, I think there might be a php problem here, but I am not sure. Also, I should mention that I did have WPMU running in my main domain prior to this in a directory called mydomain.com/wpmu but I want to have a Wordpress Mu installation in a separate subdomain like I mentioned.

Does anybody have an idea as to what could be the problem. Any help would be appreciated.

Hi,

"cannot access database" doesn't have anything to do with the permissions. On shared servers you cannot use permissions higher than 755 as you will get 500 Internal Server Error. This message means that the user/pass/database you have created in MySQL Manager aren't the same as the credentials you have in your config file for WordPress. I suggest you check the config and be sure you have the same user/pass/db that exist in your MySQL manager in cPanel.
