[Mediawiki-l] MediaWiki 1.10.0 -> "You have not specified a valid user name"

[Boyd, Josh]

I just installed MediaWiki 1.10.0 last week on a new Ubuntu 6.06 LTS
server running Apache 2.0.55, PHP 5.1.6, mySQL
5.0.24a-Debian_9ubuntu2-log.

 

Everything was working fine last week and this weekend until Sunday,
when it became impossible for any users to login, including WikiSysop.
The following error message comes up:

 

Login error: You have not specified a valid user name.

 

This happened to me before on an old box, so I got a new box and did a
new server install on it.

 

Any help would be greatly appreciated.

 

Thanks.

 

Josh
