Random Blank White Pages, Especially In The Admin Area

[Luke]

Is this happening to you?

Maybe trying to edit a post or something in the back end you get blank white pages?

Lovingly (not) referred to as a WSOD (White Screen Of Death), I recently had this exact issue.

With all the moving and shaking in the main WordPress trunk, and then WordPress MU trying to keep up with it in its own trunk, this sometimes slips through the cracks.

Do you happen to be running PHP 5.2.x?

This Track Changeset should fix it for you, if it does not already exist.

Of course, make sure you don't have those changes already.

That being the function in wp-included/functions.php, and the filter that calls it.

Yes. I get it both regular WP and MU.

I'm guessing something gets tripped and it goes to a die();

Hmm, I;'ve never seen it.

[quentin]

me neither  neither was it reported to me...

It comes up every once in a while over at wp.org and wp.com.  I don't remember a solution.  Blank lines/ spaces at the end of a plugin or the config file ring a bell though....

It has to do specifically with PHP 5.2.x, and the referenced trac ticket solves it.

I haven't looked to see when Donncha added it in, but it was added in sometime in the 1.2.x branch.
