Can't access WP-Admin page because of error - wordpress

I am trying to edit a website I made in Wordpress, but when I go to the example.com/wp-admin/ to get to the Admin,
I get the errors, and so there is no way to go into Wordpress to edit the site.
I even changed the WP Theme back to the default TwentyTen through PHPMyAdmin, but that didn't help.
What can I do? Here is what I get when I try to go to wp-admin page:

I just set WP_DEBUG mode to false and that skipped it all and got me to the WP-Admin login page.

Just find the pluggable.php and after <?php please add this ob_start(); and save. That should work.

Removing "blank lines" from function.php file and check it now issue is as it is than after check plugin folder >> disable plugin and check
Refresh your Browser, and the original error message Should go away.

Undefined array key in wp-includes/class-wp-list-util.php

I'm getting an error when I click on the abandoned cart email link.
Warning: Undefined array key "line_total" in wp-includes/class-wp-list-util.php on line 169
There is 4 method to fix this error:
1: Go To Dashboard -> Update -> On You have the latest version of WordPress, click Re-Install Now.
2: try to use the default WordPress theme to see if your current theme causes this error.
3: Sounds like you are using an incompatible plugin, try disabling plugins one by one to find which plugin causes this error.
4: Finally you may disable wp_debug to ignore this error, go to wp-config.php
and find and set it to disable like the example below:
define( 'WP_DEBUG', false);

Unable to get to wp-admin log in page

Hi I have recently tried to log in to my site and I keep getting the following error:
Warning: Cannot modify header information - headers already sent by
(output started at
/homepages/6/d700752663/htdocs/clickandbuilds/OnyxMotorsCompany/wp-content/themes/cardealer/includes/base_functions.php:1)
in
/homepages/6/d700752663/htdocs/clickandbuilds/OnyxMotorsCompany/wp-includes/pluggable.php
on line 1210
I have not made any changes to website. The website itself works fine however I cannot get to wordpress dashboard either via wp-login and wp-admin.
Any idea? Thank you
Open base_functions.php & try and add following code on top.
<?php ob_start(); ?>
You have already marked path to file: /homepages/6/d700752663/htdocs/clickandbuilds/OnyxMotorsCompany/wp-content/themes/cardealer/includes/base_functions.php
I hope it will help.

Moving Wordpress website to another server

A friend of mine asked me to move wordpress website from development server to production. I've copied all the files, backed up and restored database. After that I'd changed sitename and home values in database (_options table) to new domain and it started. Though only home page is working fine. When I navigate to any other page it gives me 500 error. In error_log I got following errors:

Paths that cause errors are related to development server and I can't find where to change them. I'm not very good with wordpress, so I suppose that solution should be very simple.
I'm sure there is an issue with a plugin http://codecanyon.net/item/visual-composer-page-builder-for-wordpress/242431/comments?page=149 try to see if there are any hardcoded paths on the plugin dashboard.
Delete your .htaccess file then go to the permalinks page change to another permalink type save page then change back to permalink you had this will force wordpress to recreate the .htaccess file and it will allow all pages you have to show correctly on the site. :-)

Wordpress: Cannot login in after upgrade - redirects to blank page

I updated a clients Wordpress to 3.5.2 and now cannot login via wp-admin.
The login form appears but once I hit the Log In button I am just redirect to a blank page with a single . on it. Same happens if I enter the wrong password.
I have checked out the Login Trouble Codex and tried replacing the wp-login.php file and disabling all plugins to no affect. I get the same issue occuring.
Front of the site seems fine.
What appreas in debug:
Warning: Cannot modify header information - headers already sent by (output started at /home/stretton/public_html/fo/wp-content/themes/freya/lib/widgets/banners-125.php:13) in /home/stretton/public_html/fo/wp-login.php on line 369

EDIT: I have also tried:
Renaming my theme to defualt it to the twentytwelve theme
Renaming the plugins directory
Removing the widgets directory
Replacing WP-Admin with from a fresh download
No luck with these either
Rename the active theme and force a revert to twentytwelve. Theme issues can still sometimes cause admin errors. But once the theme reverts, you should be able to get into admin, even if the front end is white-screened.
To figure out what's causing the white screen on the front end (or, if needed, the backend, too) use Debug. See https://codex.wordpress.org/WP_DEBUG
Add to wp-config.php:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
and the debug.log file will be in wp-content. And/or, add this line
define( 'WP_DEBUG_DISPLAY', true);
to dump them to the browser, too.
