Warning: Cannot modify header information

[Microdot]

Hi, just installed Zen Cart and loving everything about it - an amazing package.

I've noticed that once I place a product in a category and click category link, for example 'DVD' I get this:

Warning: Cannot modify header information - headers already sent by (output started at /data02/public_html/site/store/includes/languages/english/index.php:117) in /data02/public_html/site/store/includes/functions/functions_general.php on line 44

Many thanks for your help and for such a radical shop

Thanks, I had a look but no joy, everthing looks ok in both files. I also switched templates just to test, but the problem remains.

Is that from the file on your PC, or the file on the server?

Is that the last line of the file? or how many lines are there?
Did you make any customizations to that file on earlier lines ?

Some FTP programs convert line-endings to double-space the file. Zen Cart doesn't distribute the files in double-spaced format. So if yours are double-spaced, that could be causing you some grief.

Downloaded from the server and opened in Dreamweaver.

1385 lines of code

I did but followed the Zen Cart FAQ to the letter

Ooer, Core FTP is what I use, is there anyway I can find out if this is happening?

I used Fantastico to install Zen, could this be the source of the problem?

I've often seen fantastico-installed sites end up with double-spaced files.
I usually re-install with a good set of files via FTP

A second cause of double-spaced files can *sometimes* be the accidental treatment of PHP files as binary instead of ascii (text) files. Be sure your FTP program is set to treat PHP files as "ascii" and not binary.

I also usually use FileZilla, as several other FTP programs often experience timeouts and fail to properly upload all files.

The english.php file in v1.3.7.1 is only 693 lines long. The 1385 you quoted would be double that ...


If you undo your customizations and replace your english.php file with the original ... does the error go away? If so, then perhaps your edits ended up with mismatched quotation marks somewhere ?

[Microdot]

Whoa.

Didn't realise I was using an outdated version. Thanks for that, will download and get cracking on it



I don't have the original because of the fantastico, and closed dreamweaver before i noticed the problem.

Still, if there's a newer one around I'll give that go with the FTP software you suggest. Thanks a lot for your help.

I got the same problem

Warning: Cannot modify header information - headers already sent by (output started at /home/nutricio/public_html/shop/includes/languages/english/index.php:117) in /home/nutricio/public_html/shop/includes/functions/functions_general.php on line 44

my english.php has 1835 lines, and I installed zencart from fantastico, my version is 1.3.7. what do I do?

should I delete everything and install something else?
