WordPress white or blank admin screen except the left navigation bar is a very common issue of WordPress. There are lots of users who do not regularly update their WordPress version. Now one day you logs into your WordPress dashboard and get this blank screen, no content is showing up and you are not able to navigate to any tabs or links.
Here is the solution.
- Go to ‘wp-adminincludes’ directory via FTP and download ‘screen.php’ file.
- Open this screen.php file in any PHP editor (notepad ++ or Sublime Text ).
- Go to line number: 706 and you can see this
<?php echo self::$this->_help_sidebar; ?>
- Replace the above line with this
<?php echo $this->_help_sidebar; ?>
- Save this screen.php file and upload to the same place.
- It’s all, now log into your WordPress dashboard and you can see that everything gets back.
I recommend you update your WordPress and Plugins versions regularly so that you will never have any issue at all.

Breadcrumbs is a navigation aid used in user interfaces. It gives users a way to keep track of their locations within programs or documents. Breadcrumbs typically appear horizontally across the top of a web page, usually below title bars or headers. They provide links back to each previous page the user navigated through to get to the current page or—in hierarchical site structures—the parent pages of the current one.
You can use Breadcrumbs feature in your WordPress post page or content page to show the hierarchy.
Home » Parent Page » Sub Page1 » Sub Page2
Home » Category » Subcategory » Post Name
Step 1: In your function.php file put the following code for Breadcrumbs.
Step 2: In the header.php or in your theme page put the following code to display the Breadcrumbs.
<?php if (function_exists('wordpress_breadcrumbs')) wordpress_breadcrumbs(); ?>
Step 3: All that remains to do for now, is to design your breadcrumbs with CSS. You can use #crumbs for styling breadcrumbs block and #crumbs .current for styling a current crumb.
