You login to your
wp-admin in your website.
If you can see the navigation bar on the left but you see a blank page on the right.
This is how you fix blank screen in WordPress admin
You need to have access to your files either through SFTP or Cpanel
Look for this file:
wp-admin\includes\screen.php around line 706
This line would say:
<?php echo self::$this->_help_sidebar; ?>
Edit this line to:
<?php echo $this->_help_sidebar; ?>
Save the file.
You are not done yet
Now is the time to change your crappy hosting to WPengine
