Installation to sub domain Error 400

  • febwa1976


    I get 400 error – bad request when trying to run the bb-admin/install script.

    I am installing on

    Host is ASO

    Check database username :pass 10 times.

    No trailing / at end of in config.php

    I have tried “/” and /forum/ in config file

    I am probably doing something stupid

    Any clues?

  • I had no problems with the same configuration (host site5).

    Is your config file located in the subdomain directory?



    yes its in the subdomain directory. .. I am going to try on a new domain root install.

    What is the url you’re tring to install it to? ?

    If that’s the case, you need to install bbPress in the directory on your server that that url points to. You config should then look like:

    $bb->domain = '';

    $bb->path = '/forums/';



    OK – This is what I did at the beginning.

    ASO has cpanel.

    I went to cpanel and created “subdomain” called “forum”

    When you do this cpanel automatically creates a directory “forum”

    I uploaded BBpress to this directory.

    I created a database in cpanel and completed the fields in config.php

    I tried $bb->domain = ‘’;

    $bb->path = ‘/forums/’; plus a lot of others.

    Does not work.


    I went to a current subdomain I have and in cpanel physically created a directory /forum/.

    I populated config.php with the data and it WORKS! (looks good by the way!!).

    The only thing is that my forum is at

    I cannot get it to the root at

    (by the way when I install WP to it works first time every time and I do not have to install it to, and call it from

    Sorry for the long post and hope it is clear…

    What am I missing here?

    The path is for the URL.

    So if is public_html/forums/ on your server, you still just want / to be your path because when you load it in a browser it’s:



    Soooo. It works!

    As usual it was the unexpected simple thing. My domain is at one host and the subdomain is at another. The A record was not propogating correctly. I fixed this and the install worked first time.

    Thanks for taking the time to help.
