"Cannot modify header information" error after installation

by Scherbenreiter » Thu Aug 22, 2013 10:28 am

Hey!
(Sorry I didn't open a new topic before v.v')

We've got problems with the mod, but we are sure to have installed it properly... and to be sure, we both have looked the modifications over and made sure.

Instead of the actual function, the memberlist is shown with bigger letters and an error code located over the header:
[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 4693: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)
[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 4695: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)
[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 4696: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)
[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 4697: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)

Here you can see the error code and here the memberlist itself.

With these errors, we can not enter the ACP properly. Following error code appears:
[phpBB Debug] PHP Warning: in file [ROOT]/adm/index.php on line 150: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)
[phpBB Debug] PHP Warning: in file [ROOT]/adm/index.php on line 152: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)
[phpBB Debug] PHP Warning: in file [ROOT]/adm/index.php on line 153: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)
[phpBB Debug] PHP Warning: in file [ROOT]/adm/index.php on line 154: Cannot modify header information - headers already sent by (output started at [ROOT]/language/de/memberlist.php:1)

The rest of the forum seems to work properly.
Can you help us? >.<

Hello Scherbenreiter,

Your problem is not mod related. I will try to help anyways.
The error you are having could happen for two reasons.

1. At the beginning of the line, you have a space before the <?php tag. Remove the space.
2. The file is not encoded in UTF-8 without BOM. To check if it is or to encode it, open the /language/de/memberlist.phpfile in Notepad++ and go to Encoding (at the topleft) Be sure UTF-8 without BOM is checked.

I hope that helps.

Hi, I am Lorella.
I have the same problem:
[phpBB Debug] PHP Warning: in file [ROOT]/adm/index.php on line 150: Cannot modify header information - headers already sent by (output started at [ROOT]/language/it/ucp.php:1)

I have tried the solution here write but
the two files adm/index.php and language/it/ucp.php don't have any space or line before the tag php and
the two files adm/index.php and language/it/ucp.php are uft8 without BOM.

ave you any other suggestent to solve this problem? Have I to controll space and encoding of all files?

thanks
lorella
