Answer 1

Go to your functions.php page and delete any spaces immediately above or below your PHP tags.

Answer 2

That white screen of death happened to my blog, and what I did was that I renamed the theme and plugin, and everything was back to normal.

Answer 3

I also had a blank screen for my blog. The solution was to copy up a backup copy of wp-config,php somehow the 'live' wp-config.php had been replaced with a file size of zero.

In my case I had the same problem. Helped remove the wp-config.php file. Wordpress created new wp-config.php file and wp-admin is working flawlessly now. Rename plugins, themes folder does not help.

Answer 4

In my case, I was able to see the backend, but in my front I was getting a blank page...

Nothing about debugging and disabling themes/plugins was useful...
After some research, I've realized that my index.php (located at the root directory, not the theme's one) was empty!
The only content was a message saying Silence is golden.

Using a backup I had, I could get back my original index.php and get the site working again.

Answer 5

I faced the same problem and I tried many things such as trying to login through wp-login.php instead of /wp-admin and adding ob_start() in /wp-admin/index.php (if you hit the url /wp-admin it goes for /wp-admin). It showed login page but entering the username and password shows an error like "cookies are blocked due to unexpected output".

I finally got the solution: it happens because the theme or plugins that you installed are not supported.

How to check and fix:

• Rename the plugin folder name and theme folder name. If opening /wp-admin and entering a valid username and password the dashboard is shown, then it worked.

• Revert the folder name of plugin and theme, then activate the themes and plugins one by one, cross-checking with /wp-admin. You will find out the unsupported plugin or theme.

Try turning on WP Debug. If this is happening due to a PHP error (which I bet that it is), you will be able to see what's going on and fix the error.
