Mod Note: Split from http://forum.joomla.org/index.php/topic,115866.0.html -RobS

I'm having a similar login issue, but on the administrator side.  For some reason when i go to http://www.mysite.com/administrator and enter my username and passsword it just refreshes the page and ends up at the same place.  I can login as many times as I want, but it just refreshes the page. 

I was having the double login issue on the front end, but the files posted at the beginning of this thread fixed that problem.

Any help will be appreciated.

Thanks

There can different reasons why the admin login keeps faling. One thing you could check: in your PHP configuration, session.auto_start must be switched off. If that doesn't help, please post (or send by PM) a URL where this can be seen, sometimes it's possible to find the cause just by watching the servers response to a login request.


P.S.:I would like to keep this thread related to frontend login issues. Can some MOD please split these two posts into a new tread?

I have the same problem as jkcarr2 and it gives me awful headache. I am searching for solution for three days. Somethimes I can log on, and sometimes for a half day not. I noticed that when i could not login I have the poll (enabled cookies) issue. In configuration.php I did not found session.auto_start. What else can i try?

P.S. On the same server I have another joomla folder and it's works just fine.

session.auto_start would not be in the configuration.php file.  It would be in the PHP settings. 

If you feel comfortable, try editing the ./administrator/index.php ~39 you will see

Code:
if (isset( $_POST['submit'] )) {
         /** escape and trim to minimise injection of malicious sql */
         $usrname        = stripslashes( mosGetParam( $_POST, 'usrname', NULL ) );
         $pass           = stripslashes( mosGetParam( $_POST, 'pass', NULL ) );
 
         if($pass == NULL) {
                 echo "<script>alert('Please enter a password'); document.location.href='index.php?mosmsg=Please enter a password'</script>\n";
                 exit();
         } else {
                 $pass = md5( $pass );
         }


Change it to:

Code:
if (isset( $_POST['submit'] )) {
         /** escape and trim to minimise injection of malicious sql */
         $usrname        = stripslashes( mosGetParam( $_POST, 'usrname', NULL ) );
         $pass           = stripslashes( mosGetParam( $_POST, 'pass', NULL ) );
 
         if( ini_get ( 'session.auto_start' ) ) {
                 echo "<script>document.location.href='index.php?mosmsg=PHP\'s session.auto_start setting is on.  You must turn this setting off before you will be able to login.'</script>\n";
         }

         if($pass == NULL) {
                 echo "<script>alert('Please enter a password'); document.location.href='index.php?mosmsg=Please enter a password'</script>\n";
                 exit();
         } else {
                 $pass = md5( $pass );
         }


The next time you try to login to the Administrator interface, if session.auto_start is on a message will show above the login form alerting you about the setting.

Edit: Note, you have to actually submit the form once before the message will show up.

Thanks for the replies.  I am experiencing this problem with every upgrade to 1.0.11 I try.  I was going to try changing the code that RobS recommended, but I couldn't find it in adminstrator/index.php.  Is there anywhere else it may be?

Thanks again

I found the code in administrator/index.php.  Not sure why I didn't see it first time. I replaced it, but it didn't fix.  After I enter my username and password and hit submit it goes to index2.php for a second, then just goes back to the login page.  The address bar then says http://www.wiseowlconsulting.com/admini ... to%20login.

Could you both make sure that you have cookies enabled in your browsers?  I know it sounds obvious but sometimes people forget and it happens...

About the problem at Cyb3r's site (thanks for sending me the link by PM): looks like cookies are disabled on your site at all! No cookie is set after loging in (since I got redirected to index2.php, I know the username/PW was accepted). The strange thing is this: also on the frontend site, no cookies are set! Do you manage to log in to the frontend at all? I guess not?

To jkcarr2: Cookies get set on the frontend of your site. Can you please take a look at your php config (usually php.ini), and make sure the setting for session.use_cookies is set to 1? Also, make sure the session path is writeable. E.g. if your servers hard drive is full, it can't store the settings for your session.

One thing that happened to me once was to encode the lang file on UTF-8 with Windows NotePad, and didn't noticed, it adds some non-printable characters before the start of the text. Those non-printable chars fill the output buffer avoiding the site to set the cookies.
Here's how to check if this is your error:

With FireFox disable JavaScript and try to login - This is to avoid JS to send you back to login form.
Check if you have an error like "Can't set cookie. Headers already sent...."

To correct:

Open your lang file with a another (more decent) Text Editor, like EMACS (for Windows ftp://ftp.gnu.org/gnu/emacs/windows/) and delete any weird stuff before

I checked the php.ini file and it had session.use_cookies set to 1.  I also tried the disable java script.  It didn't refresh the page like usual, but it didn't let me in the system either.  It just took me to a blank white page.  I didn't see anything about errors.  I'm new to most of this stuff and am not sure how to check to make sure the session path is writeable.  I use a server through a hosting company (powweb) 

Also tried to PM you earlier friesengeist, but for some reason I keep getting an error saying I can't PM.  Is there something I have to do to enable that feature?

Thanks again for all of the help!

Try check your server's error log.

Good catch, sirathur!

I just checked Cyb3r's site by sniffing the request, and indeed, there seem to be some BOM bytes at the beginning of the response data. No error messages though, probably display_errors disabled, like on every good production site. Cyb3r, could you please also check your error log?

Sorry about that, for protection against spammers, you need to have at least five posts here at the forum before you can send PMs. So now you should be fine ;) I just forgot about that.

This happens when i try to log as administrator (from error log):
Code:
[21-Nov-2006 07:55:49] PHP Warning:  session_start(): Cannot send session cookie - headers already sent by (output started at C:\apache2triad\htdocs\holy-colly\includes\version.php:1) in C:\apache2triad\htdocs\holy-colly\administrator\index.php on line 91

friesengeist, I send you PM with atached index.php and index2.php. Keep in mind that I changed part of code with RobS code (discrbed few posts earlier).

Looks like you need to re-edit your version.php. Like sirarthur states:

At least you know where it's coming from now ;)

When opening with WeaverSlave (http://www.weaverslave.ws, my favorite editor), the beginning looks like this:

Code:
<?php


You need to save the file without the BOM (Byte Ordering Mark), either with UltraEdit, if you can specify how it should be saved, or with another editor.

Enno,

Any idea if jkcarr2 his report is actually a bug? Or more of a setup problem. I'd like to determine if I need to follow up on this topic.

Thanks Robin

No, it's a setup problem, session path not writeable. I got some error logs from him. No need to take this "under review" or anything ;)

The domain doesn't start with localhost (localhost represents you home computer and works only in you net). Replace 'localhost' (in link) with your domain or IP. But this will not solve your problem.

Find version.php with search/find apllication.
