Fix the errors

stevenc commented 24 March 2010 at 12:31

That error message "Warning: Cannot modify header information - headers already sent" means that the sever has already output content to the browser, but some other function is trying to call the header() function AFTER, which is not allowed.

Basically, you need to fix your SQL errors first. You could also suppress the display of error messages (which you should definitely do for a production site) and check for them in your server log file instead.

If you need further assistance, just Google for that error message. It's not a Drupal-specific error, so there's a LOT of information out there on it.

I had a header error when I

mlosee222 commented 24 March 2010 at 18:40

I had a header error when I switched hosts. In my case, it was due to blank space at the end of settings.php.

Make sure there aren't any spaces at the end of your settings.php. Even one little " " is enough.

Hope this helps.

Holy sweet mother of... thank you!

This is an 8 year old thread but I have to say thanks. This is the exact problem I had when moving from hostgator to dreamhost. Something wrong with the settings.php that was previously working perfectly. Downloading a fresh drupal 6 settings.php and uploading over top of the old one fixed this error. That was 3 hours of banging my head on the keyboard. Time for a drink.

try repair and optimize the database tables

lipinponmala007 commented 7 April 2010 at 11:33

i had this error and i solved this by running the following in the terminal..

mysqlcheck -u root -p --auto-repair --check --optimize --all-databases

or check the following link

please place a feed back if this works.

The "Headers already sent"

modul commented 7 April 2010 at 11:34

The "Headers already sent" error also shows up when you have something (even a space...) after the end of php code, so after the ?>

Have the same problem

I hope anybody ever got over it as I've got no more clues =[

I had the same error/warning

mmaul commented 8 May 2010 at 19:20

I had the same error/warning messages today after upgrading a client’s system from 6.10 to 6.16. Database was exported with Backup & Migrate, and re-imported with *cough*PHPMyAdmin*cough*. Optimizing tables worked like a charm, so thanks! (Though I am still investigating WHY the errors popped up in the first place…)
