Typically, if a blank page appears, an error has occured, and should  be displayed or logged somewhere.  Have you checked all the logging / show errors settings in PHP and Apache, etc.? A bit of googling should help you find out where these are (hard for me to point you in the right direction since it depends on your server set up).

Did you try looking in the PHP logs?

Are you able to get any errors displayed on the screen? Might be worth intentionally creating an error and ensuring that you can see that displayed on the screen.

If not, have a look at PHP error logging and ensure it has sensible defaults (display_errors, etc.)

I was able to create a PHP error from within the civicrm.php Wordpress plugin page by executing a function that didn't exist. I saw that get logged to my ngnix log.

I narrowed the problem down to this bit of code:
   
if ( $this->isPageRequest() && !in_the_loop() && !is_admin() ) {
      return;
}

I put a print in there above the return statement like so:
if ( $this->isPageRequest() && !in_the_loop() && !is_admin() ) {
      print "isPageRequest=".$this->isPageRequest().", in_the_loop=".in_the_loop().", is_admin=".is_admin();
      return;
}

and on pages that are blank I get the following:
"isPageRequest=1, in_the_loop=, is_admin="

Looks like Wordpress is broken maybe?
