WordPress MU error: No WPMU site defined
I just got this error trying to install Wordpress Multi-User on this host:
No WPMU site defined on this host. If you are the owner of this site, please check Debugging WPMU for further assistance.
Confusing error, especially since I previously installed it successfully. Fortunately, the excellent WordPress forum for MU helped me: just remove the wp-config.php file. Seems like I forgot to configure WordPress the first time I tried WPMU, which was the correct way. You should not upload a wp-config.php for WPMU, since it is generated automatically.

Thx fro the tip.Its just fro multi user right..anything special

Yes, thanks for that pointer. Anyone used to installing wordpress will automatically edit the wp-config file, and the docs don’t say anywhere that you *shouldn’t* do this for WPMU (or not that I can see…). Hurdle 1 complete :)

Mark, thath’s the easy part ;)
Good luck setting the rest up!

Well so far so good. I’m using plesk on this particular site which is making the wildcard host setup a bit of a challenge. but I’ve edited the apache config for this and it seemed to fix that — just have to remember not to use plesk for tweaking that vhost!
But it looks like a pretty good application - I’m impressed so far (after the initial hurdle).

Been everywhere looking for help. Damn! All I needed to do was nothing, just upload all the wpmu files and access the install page. Oh, why did I ever mess with the wp-config.php file at first.
Thanks for the tip! It helped a lot!

Hi,
After unzipping wordpressmu I deleted wp-config file and now I am getting this error:
Installing to http://localhost/ is not supported. Please use http://localhost.localdomain/ instead.
