[Plugin: DBC Backup 2] Can't log in to admin panel

Hi Squid

First .. sorry you seem to be having issues with your new build of WordPress. Does the problem go away if you remove those lines from the .htaccess?

I’d be confident that the problem is not with DBC Backup 2 – because it sounds like you did the right thing in the .htaccess file – but did you then change the Permissions to something too restrictive (ie 400 instead of 664/ 667) see also https://wordpress.stackexchange.com/questions/58391/is-moving-wp-config-outside-the-web-root-really-beneficial/58820#58820

Second … you can always FTP into your site and rename the plugins folder to plugins.old and create a new folder called plugins — or if you prefer, just delete the DBC-Backup 2 folder.

Let me know what you changed as I’d believe its not in DBC-Backup

hope that helps?

Hi and thanks for the swift reply

Yes I have deleted those lines from htaccess file… Taking off the guard here for a moment.

Let me summarise in full as I have no experience in programming, maybe you can help me out here. Would appreciate it very much.

*Warning: Cannot modify header information – headers already sent by (output started at /home/xxxxxx/public_html/wordpress/wp-config.php:1) in /home/xxxxxx/public_html/wordpress/wp-includes/pluggable.php on line 881*

pluggable.php 881:

function wp_redirect($location, $status = 302) {
global $is_IIS; 

$location = apply_filters('wp_redirect', $location, $status);
$status = apply_filters('wp_redirect_status', $status, $location); 

if ( !$location ) // allows the wp_redirect filter to cancel a redirect
    return false; 

$location = wp_sanitize_redirect($location); 

if ( !$is_IIS && php_sapi_name() != 'cgi-fcgi' )
    status_header($status); // This causes problems on IIS and some FastCGI setups 

header("Location: $location", true, $status);
}
endif;

Now wp-config usually refers to hidden whitespace at the begining of the file or at the end but I have checked this and even inserted new wp-config file so the problem is not there. It has something to do with the latest wordpress version and the code dbs installed. I am using the latest version wordpress 3.4.2. My site seems to be working just fine but the error prevents me getting in to the login page which means I can’t admin at all or uninstall the plugin which seems to have triggered this problem. I have checked the wp.config file hunderds of times with HTML-kit tools and there is no visible whitespace at the begining nor at the end of the file. I have:

1.Checked the whitespaces from wp-config file with HTML-Kit tools
2.Downloaded and inserted new fresh wp-config file
3 Deleted and then reinstalled the dbc-backup-2 directory via ftp
3.Disabled the plugins directory by renaming it

…and the error still remains

The only thing left for me to try is this code someone posted on wordpress forums claiming he had solved this problem by inserting the following code to the wp-config.php file:

<?
//dont use header function in wordpress-wp_signup.php
global $domain;
global $path;
//change urlnew variable as per requirment
$urlnew = "https://".$domain.$path."/wp-admin/admin.php; 

echo "<script>";
echo "location = '$urlnew';";
echo "</script>";
echo $urlnew;
?>

but I am reluctant to add code as I am not familiar with html or php, do not exactly understand how this code functions, do not have detailed instructions where to place it exactly and most of all just because inserting new code on top of a broken one doesn’t seem to be good idea. Any suggestions?

I have read more than 50 posts on this topic and the problem seems to be with contradicting code in wordpress, printing output (text) to the browser, but then for some reason redirecting the user (with wp_redirect) away from that page before the whole page is rendered.

Do you have clue which part of the plugin might have caused this? I mean it didnt install correctly as immediately after I installed it in the admin panel i got logged out with the eroor message mentioned above.

Hi Squid

Suggest you FTP to your site and rename themes folder to themes.old and create a new folder called themes

You should now be able to get to wp-admin and you can then install the WordPress Twenty Eleven theme and check that everything is working fine.

BTW … one of the most common issues you can have with WordPress are from themes, using old themes or making changes to your theme files.

HTH

Didn’t help. Disabling plugin and theme directories didn’t help. What about that code to disable the header function in sign up? I assume it does no harm to the site as it apparently only applies for the sign up page? Alternatively, I found this post for another thread concerning this issue and for another way around this predicement:

“Your theme is printing output (text) towards the browser, however for whatever reason WordPress is redirecting the consumer (with wordpress_redirect) from that page prior to the whole page is made. You cannot start printing output after which redirect, or you will get the mistake the thing is. That is what Paul Muck was bothering in the comment.

Ken Whitened said having a reference a publish having a similar problem. I have fixed this during my own experience by loading the creation of the script.

Inside your theme’s functions.php file (which will get incorporated each time your theme’s pages load), put:

view plaincopy to clipboardprint?

01.//allow redirection, even if my theme starts to send output to the browser
02.add_action('init', 'do_output_buffer');
03.function do_output_buffer() {
04.        ob_start();
05.}

Now, even when a part of your theme begins to transmit input the the browser, PHP will not send that text before the page is fully loaded, which enables WordPress to redirect customers if required included in its very own logic.”

My only problem with both of these codes is that I do not know where to put them exactly.

I got it fixed. It was BOM which couldn’t be detected or fixed with notepad, notepad++ nor Html Tool Kit. I am not sure if my swedish UTF preferences has something to do with it. Anyways, I found the bugger by opening the config.php file in c-panel and with ANSI (1983) out of sheer desperation. Had to download Hex Editor XVI32 to rid of it.

Thanks for letting me know … so it was nothing to do with the DBC Backup 2 plugin.

As a piece of advice, as you seem new to WordPress … you should follow the cardinal rule … which is never change WordPress core files because the next time WordPress runs a core update you may find that your changes in core files are deleted.

Good Luck ??

Just a heads up! I had installed DBC Backup 2 on my sites. After one of my sites was hacked and DBC automatically backed up the hack I decided to try a different approach and so I deactivated and deleted DBC2 on both sites but left the backup files of the unhacked site in place. Wordfence security has recently alerted me to suspicious activity on this (previously clean) site and I found the malicious code in the DBC directory. I deleted the whole directory from my site via control panel but I still have many, many hits (mainly from China) trying to access my site through that bogus file. Is this a possible hole in DBC Backup 2?? The makers of this plugin need to take a look. I don’t want to say the plugin is bad! I just want to let you know what happened to me.

@grannyberry … Sorry to hear this …

First, where did you download DBC Backup 2 plugin from please? If it wasn’t on www.ads-software.com then I am very concerned

As DBC Backup 2 just creates a backup of your SQL database to your webserver – no userID, passwords or anything personal to you is stored by this plugin.

At first glance, it would seem that someone hacked into your site and saved the code into my plugin directory – just to hide it there from you.

I’d very happy to look at this further … can you contact me directly via my website wordpress.damien.co

Thanks

Damien
