OpenID login failed: Invalid openid.mode '<No mode set>'

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Trying to login using OpenID (or add OpenID via admin panel). I was 
trying livejournal.com and blogger.com IDs, both of which authenticate 
elsewhere. I use custom theme, but when checked on Default WP Theme I see 
the same.

What is the expected output? What do you see instead?
Well, the expected behaviour is to see the user logged in. however WP 
brings back the login screen wth the error as noted above.

What version of the product are you using? On what operating system?
Both latest WP (2.8.2) and OpeniD (3.2.3) on hostgator. com account (php5, 
all systems nominal, XRDS present)

Please provide any additional information below.

Allright, there seems to be more.

I can use this OpenID plugin to authenicate on *another Wordpress blog* but not 
much
elsewhere... In which case if I use my blog address <a href="http://sunshine.by"
rel="bookmark" title="Гей сайт">sunshine.by</a> - it just stops.

The output (where it should redirect to the site requesting OpenID) is 'This is
OpenID server. Nothing to see here.. Move along'

There is something wrong with the whole thing, I take it!

So am I alone with the problem or is there anything you can do about it?

I know that there are people that have the smae problem.
Anyway, I have referred to Hostgator.

Are there any server settings apart from 'nominal' that have to be present?

Where are you hosted, Rafiki - if that is no secret?

U-huh.
Well, Rafiki, just in case - have you seen any backtrack pings to your blog of 
lately? 
Even within your own blog?

I am online with the tech support (well, online is a bit of exaggerration) - 
and need 
as much information as possible. This culd be the key - they may not sove the 
state of 
the server, or accept any outside calls - or anything of the like. I do not 
know, but 
try to fix it. So? Any trackbak - of late?

Just double checked my mail - and we might be in for a solution!
Just another five minutes - please!

no backtrack pings and i am waiting with hopeful anticipation for a positive 
resolution

Rafiki, I am sorry I did not answer straight away:

Solution is easy:

It appears that OpenID was triggering a mod_security rule set by the hosting 
company. 
Simple letter rto support solved mine.

However, the issue is ver yspecific and may not be recognised straight away by 
the 
support personnel, so I suggest you check here:

issue.  
Thanks!!!

please report back here if it does indeed turn out to be a mod_security 
conflict.

That did the trick!  Yippee!

@cyrill kalita, CERTAINLY ... just tell me how to do it and you got it ... no, 
really
...  i don't really know how to do that from here ...  But, i will add a blog 
entry
about it.

this doesn't seem to  be a mod_security issue. I have tried by disabling 
mod_security 
altogether and still no avail.

OpenID authentication failed: Invalid openid.mode ''

^^^ thats the error I get. Just in case. 

If anyone know what else can be the cause and how to fix this would be greatly 
appreciated. TIA

I'm also seeing this message when I try to use my site as an openid provider. 
I've 
tried uninstalling and reinstalling the plugins, clearing the OpenID cache, 
deleting my 
list of trusted sites etc. but I'm still getting the error message "This is an 
OpenID 
Server.
Nothing to see here… move along."

I'm on a server at Rackspace cloud (that I administer myself), running 
Wordpress 2.9.2, 
OpenID 3.3.2 and XRDS-Simple 1.0
