Have you installed an extension like http://extensions.joomla.org/extensions ... ogin/10391 ?

Put your url into http://sitecheck.sucuri.net/scanner/ and see the results.

PM me the url if you want to ?

I don't know when it happend. I got some email spamming problems and an evil index.htm fil on my site some day ago.

So i thougt it be good to change admin password.
After changing the password, i still could logon with the old password, Thats when i stating thinking something was wrong.
So then i just tryed to login to the adminsite. at http://www.mysite.com/administrator/
using only admin and din't type any password. and i could login.
or i can type what ever i want in the password feild and still login.

I tested form the fornt page, worked there as well.
So i disabeld the admin acount for now.
but any users can also login using just by using there username.

Tested it on serveral browsers and computers.
So don't think its cache session problem ?

Can there be some problem with som .php files?
Don't know were to start looking.

I can confirm that just by putting the username in without password will login to the backend.

I have found a component that I think is the cause or could be. I would like permission to uninstall it and reupload the Joomla core files.

  • Installed Akeeba and backed up
    Backup showed successful with warning 'Unreadable file.../www/components/com_jcomments/jomsocial_rule.xml. Check permissions'
  • Installed Admin tools and used it to reinstate Joomla core files
    it stopped part way with error about opening a template image file for rewrite.
    Second attempt wrote the files
  • Logged out tried logging in without password and with any alphanumeric. Tested on several Browsers. Appears to be fixed now.
  • Backed up site again
    same warning but shows successful. try the jpa on your PC to see if it is good.

Try the site now. No guaranties but it looks OK now. A lot of security suggestions can be found at viewtopic.php?f=432&t=475313 . Ignore the parts about deleting because that is for hacked sites. Concentrate on the security suggestions.

Thanks go to mandvill for this ... PM's helped locate the error.
