login in joomla does not login moodle

HI!
Me again

joomla! version: 3.3.1
Moodle version: 2.7
Joomdle version: 0.95

I have this problem, when a user logs in my joomla site, and then clicks the link to moodle site he is not logged in the moodle site.
In fact, sometimes (not always) once in moodle, if the user tries to log in in the moodle side he gets this screen.


If the user clicks on "continuar" (continue) it leads to the main page and he is logged. This is in debug mode.

My main concern is why once logged in joomla the user is not logged in moodle, i guess this error page is not shown when moodle is not in debug mode

Any suggestion?

Thanks a lot

As you say , error will go away if you disable debugging.

As for why SSO is not working: try changing value of redirect-less SSO.

I changed value and now when I try to login in joomla it displays a message

Error: ajax request failed!

After that The user is logged in joomla, but you have to refresh to see that. And still not logged in moodle

Are you using normal joomla login module? You should try with it first, to rule out 3rd party problems.
