Cannot modify header information – Error

Hi dimitris33, thanks for replying. The twentyfourteen theme displayed fine, it was only after I had activated it that the screen went blank (in the dashboard).

I use Firefox and I just tried to log into the dashboard in Chrome and the login page is blank – but it is fine in Firefox (must be cached as it doesn’t work in IE either).

Here is the site – https://www.bmsaccountants.ie, the blog is install on this page – https://www.bmsaccountants.ie/bms-blog/

ok, if the problem is the code you can

1.remove it
2.fix it

https://codex.www.ads-software.com/Automatic_Feed_Links

open your functions.php

find this “automatic_feed_links”

delete it and add

add_theme_support( ‘automatic-feed-links’ );

let me know how it goes.

ps.your theme looks custom.

Thanks for the reply, that has fixed the deprecated error message, but still after clicking update on a post I get a white screen with the following error: (WP_DEBUG is set to true)

Warning: Cannot modify header information – headers already sent by (output started at /usr/local/pem/vhosts/236304/webspace/httpdocs/bmsaccountants.ie/bms-blog/wp-content/themes/bms/functions.php:427) in /usr/local/pem/vhosts/236304/webspace/httpdocs/bmsaccountants.ie/bms-blog/wp-admin/post.php on line 233 Warning: Cannot modify header information – headers already sent by (output started at /usr/local/pem/vhosts/236304/webspace/httpdocs/bmsaccountants.ie/bms-blog/wp-content/themes/bms/functions.php:427) in /usr/local/pem/vhosts/236304/webspace/httpdocs/bmsaccountants.ie/bms-blog/wp-includes/pluggable.php on line 896

I am chatting with my hosting company too, there seems to be a slight issue with our error logs, as in they are huge in file size. I’ve checked and one re-occurring error is:

[Thu Feb 06 14:12:58 2014] [error] [client 78.153.216.42] PHP Warning: is_dir(): open_basedir restriction in effect. File(/) is not within the allowed path(s): (/usr/share/pear/:/usr/share/php/:/usr/local/pem/vhosts/236304/) in /usr/local/pem/vhosts/236304/webspace/httpdocs/bmsaccountants.ie/bms-blog/wp-includes/functions.php on line 1366

So I am hoping they can help me with that.

Seem to be having a problem with this line in the wp-includes/functions.php file line 1366:

// We need to find the permissions of the parent folder that exists and inherit that.
	$target_parent = dirname( $target );
	while ( '.' != $target_parent && ! is_dir( $target_parent ) ) {
		$target_parent = dirname( $target_parent );
	}

never touch wp core files.

I think the problem is somewhere to tell you the truth.i am guessing that your theme’s code must be updated to work with 3.8.1.

just to be sure, you can check for spaces or open php tags in your functions.php but i doubt that the problem is there.

It looks like the code in the last reply is causing a lot of errors in the error logs (repeatedly the same error with the same time) and this is causing a large file size, so for now I am going to remove the files from the server until tomorrow, hopefully I will have more of an idea how to stop this by then.

allan,

i saw again the path to the error and it is in wp-incudes/functions.php

this is a core file, i thought it was your theme’s functions.php and the changes i ask you to make was for that file, not the core file.!
sorry about that.

i’ll check again tomorrow if you made any progress and see if i can help you.

This is not a core WordPress issue. Can you replicate the problem using the default Twenty Fourteen theme with all plugins deactivated?

Hi dimitris and esmi.

I haven’t changed any code in the wp-includes/functions.php file as I know that is a core file.

I was chatting again with the hosting company and they had to get an engineer to look at the problem. The error logs on the server reach about 80GB earlier, when they reset the error logs (at about 6pm) they went to about 90GB in about 2 hours. The error was just repeating itself constantly even after I had removed the files from the server.

I think it was still happening with the twentyfourteen theme installed.

I will try a fresh install tomorrow and see how that goes, this is the first time I have seen something like this. I have installed about 20-30 WordPress sites but never seen this.

Hi esmi.

I had found another error in the error_logs this morning that was repeating itself quite a bit and after looking into it more, I stumbled upon an .htaccess file in the root of our webspace which was part of a Magento install before that someone had done.

Renaming the .htaccess file stopped the error this morning, so that was good.

Here is the error:
Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

I’m just after installing a fresh copy of WordPress and everything is working smoothly, I’ve checked the error_logs and they are all good.

Maybe the theme being used in the old installation and the .htaccess file from that Magento install had something to do with the error_logs being spammed.

Looks like this topic is resolved ??
