Cannot send session cookie - headers already sent

Post by cigsmh » Sun Mar 02, 2008 1:38 am

Hi All,

My remository component doesn't work properly and as I was told it has something to do with cookies.
Recently I saw the following warnings on my Remository admin page, and I hope that you guys can tell me what is going on with my cookies.


Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/handyman/public_html/includes/joomla.php:4148) in /home/handyman/public_html/includes/joomla.php on line 800

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/handyman/public_html/includes/joomla.php:4148) in /home/handyman/public_html/includes/joomla.php on line 800

Thank you,

Igor

You've an extra blank line on a php file that you've edited recently, possibly includes/joomla.php, but not necessarily.

If you've edited a php file, config or a remos file perhaps laterly, load it into an editor and see if there is a blank line either before the <?PHP or after the final ?> at the bottom of the page.

Some website editors do like to add an extra blank line each time you edit a php file in them!

have you modified your system so it does not show any more globals=on?

please check for any blank lines at the end of your globals.php file and if so remove those

I was struggling with the above problem today.

I deleted the blank line at the end of my globals.php and everything is grand now.

Thanks for the post.

I had this problem as well..Don't know if this will help. I was getting an intermediate page with an error between index.php and index2.php. It appears for only a few seconds ..So I took a screen shot of it..It referenced an error in class.phpmailer.php.

I fixed it by removing trailing empty lines in /includes/phpmailer/class.phpmailer.php and /includes/phpmailer/class.smtp.php

I also did the bit about placing the php.ini file in the root joomla folder and the administrator folder
see here for more info.

Just fix it.
I saved php file (edited with notepad) in ANSI format, not UTF-8 which was default.
SO if you dont have an extra blank line, you should try this one.

A late post in this thread just to confirm that saving with Notepad using ANSI format as described above actually does help.

Thanks for the hint - it drove me nuts.

Re: Cannot send session cookie - headers already sent

The following errors happened after finishing the last step in the joomla installation, which included deleting the installation folder and then creating a new configuration.php file from the text supplied in the last dialog box. I opened my site in joomla and got these errors:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by...

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at ...

Warning: Cannot modify header information - headers already sent by ...

I found this forum and decided to try saving the configuration.php file in a different way which was unicode utf8 no BOM and it worked!

Guys the problem is about the corrupted characters before <?php . Those appears when you changed encoding ANSII to UTF-8. Edit your configuration.php with a HEX editor or re-encode it with Notepad++ and select "Encode in UTF-8 without BOM"

Hi,

I don't know if this helps, but I battled this problem for hours yesterday. Eventually, I figured out it was related to the length of the domain name.

I was installing a unix based virtual host and if I installed a fresh just downloaded latest version of Joomla on a domain that was 7 characters long, it would work, but if the domain was longer such as another domain I had that was 10 characters long it would not work.

It drove me crazy, until eventually I installed another copy of joomla in another directory on my shorter domain and copied the joomal directory to the longer domain name once it was configured.

This seems to do the trick for me, hope this helps.

Okay, that wasn't as good as an idea as I thought.

When you want to install any extensions, etc it referers to the original location I installed it in.

Anyone else figured out how to fix this issue?

Yes that's right. I had the same problem and i was quite confuse. After a lot of research i found this information then i fixed the problem.

I hope that this will save you time and frustration.

I am having this problem:


Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/syna2358/public_html/index.php:1) in /home/syna2358/public_html/libraries/joomla/session/session.php on line 423

I have not edited any files - this just happened out of the blue on four completely separate Joomla installations.

Any ideas?

re: Previous post

I check the file the error is referencing, but there doesn't seem to be anything wrong with it, and it's encoded properly. I've never opened this file before. I'm lost.

Just for clarity, this troubles coming from something effort which try to print something!

Probably this is bug In Joomla.
You can post this bug here Joomla! 1.5.x Bug Tracker.
If you want to try to fix it you can debug your files and watch for mistakes described in link in my post above.

But why would it start just out of the blue on some installations and not others? And on installations that have been untouched and working fine for months?

Thanks that changing the file format of the configuration file had resolved my issue as well.

Thank you so much. Saving as ANSI worked for me too. I had edited config file in Dreamweaver so not sure if that's where it became UTF-8. Must start using notepad++

This worked for me...thought I would clarify a bit
  • Open your configuration.php file in "htdocs/website" with notepad++
    On the menu bar, drop down "encoding", change it from Encode in UTF-8 to Encode in ANSI
    Save the file
    Restart Apache
    Profit!
Thanks all!

UTF8 without BOM

for special chars! äöü
