Warning: Cannot modify header information

Try reviewing Solving “headers already sent” warnings

I’ve tried it..

in pluggable.php, and i’ve checked for
<?php
?>
in the files that are have the error..

And it still doesn’t work..Is there any chance i can send you my password to see what is happening? I’m searching for the resolution of this problem for some weeks, i’ve tried lots of things…

Forgive my poor english

PLEASE could somebody help me???

Did you do ANYTHING to wp-config.php before this happened?

thanks for your response mechx1..

the person responsable for the site made a backup (last week).. and he added the new theme we bought (regolith).. after that, it stopped working… i’ve uploaded the new wordpress 3.9, but the error persists..

it’s the first time I work with wordpress, so i’m really lost here..

i’ve given my client my word that I would fix it, but it really seems impossible..

It is just code, a fix is always possible.

I would check in with tech support at themeforest to see if they have any ideas. Since that update is the last thing that happened, it is the first place to look.

Your error message would indicate a space or some set of HTML tags appearing before the opening <?php in wp-config. I gather from your previous posts that you are sure the problem is not there.

Does your wp-config file have a CLOSING ?>. If it does, consider removing it temporarily and re-loading wp-config. It is not strictly necessary, and may be causing this error.

opening :
<?php
/**
closing:
?>

I tried removing it.. And uploading it again…

This is really giving me an headache..

I’m sending an e-mail to the support from the theme i’ve bought..

Lets see if they can help me.. Anyways, if I sent you the access info could you give a look on it for me? I work with HTML/CSS for some time, but never had worked with wordpress.

This is so confusing.!

This error normally generate due to extra space outside <?php ?> braces. If you can’t find spaces, you can…
Try below code…

In your theme’s functions.php

<?php
ob_start();

your functions and other code here.....

ob_clean();
?>

add ob_start(); at top of file and ob_clean(); at bottom of file.

Hope it works for you…

Shail.. i’ve done it the way you said..
@ functions.php:

<?php
ob_start();
/* Registra Menus */

---code----

add_filter('excerpt_length', 'new_excerpt_length');
ob_clean();
?>

and the error still persists..

I’ve contacted the people who made the alterations before the error, and themeforest support. I’ll tell you guy’s if it worked..Thanks for answering

Anyway, if someone wants the password 2 have a look in what could be happening.. I’ve got no clue, it’s the 1st site I work with wordpress ..

I really need help in just fixing this problem..

I wouldn’t afford paying for someone to fix something for me.. Thanks for the links..

I’m going to wait for an answer from themeforest, and from the guy who created the site (i’m starting to use a new theme, he installed it and everything went wrong)

Thanks..

Paste your functions.php in pastebin and please provide link here…

Thanks Shail

Its look like all perfect in functions.php

What i suggest is install new wordpress and then upload theme… And if it works than one by one all plugins….
This is what have esmi suggest but try it once clear all cache and try again…
