TOPIC: Solved-- Warning: Cannot modify header information

Solved-- Warning: Cannot modify header information 18 years ago #984

First, a huge thanks for this program and especially the changes in the newer versions!

I recently upgraded JoomSEF, and would love some help with a problem I am having.

My normal workflow is to copy my on-line Joomla site, OutdoorPhotoOp, to my home computer (I use WAMP for the local installation) as part of normal component testing prior to going live.

I can install JoomSEF on my local server and it works fine, and I can install it on my website and it works fine. However, when I move it from the web to my localhost, I get the following errors on the homepage:


Warning: Cannot modify header information - headers already sent by (output started at C:wampwwwoutdoorphotoopadministratorcomponentscom_sefsef.class.php:1501) in C:wampwwwoutdoorphotoopincludesjoomla.php on line 697

When I try to view articles, I get this error:

Array ( [0] => option [1] => oregon [2] => timberline_lodge.html )
Are we debugging???
Killed at line 302 in joomsef.php: HEADERS ALREADY SENT (200)
URL=localhost/outdoorphotoop/index.php?optio...&Itemid=100:
OPTION=com_content:


Any suggestions on how to get a copy of my web installation to work on my local computer?

Thanks!!!

I found where my trouble was coming from. I had read prior posts on this forum about the &quot;whitespace&quot; with language files, but when I checked them there was no whitespace. This post on Geeklog helped me realize that the whitespace was in the first file listed in the error, not the second. I had to remove a single line from the end of three files and then the problem went away.

Thanks!
