If you getting a blank screen  that may be because of 2 reasons   Browser blocking the Frames from being displayed  In some browsers the frames are considered as unsafe  To overcome this you can launch the frameless version of phpPgAdmin by http   -your-domain-name- intro php  You have enabled a security feature in Nginx for X-Frame-Options try disabling it

None of the above answers worked for me - PHP was properly rendering everything except pages that relied on mysqli  for which it was sending a blank page with a 200 response code and not throwing any errors  As I m on OS X  the fix was simply  sudo port install php56-mysql  followed by a restart of PHP-FPM and nginx   I was migrating from an older Apache PHP setup to nginx  and failed to notice the version mismatch in the driver for php-mysql and php-fpm

Also had this issue and finally found the solution here  In short  you need to add the following line to your nginx fastcgi config file   etc nginx fastcgi params in Ubuntu 12 04   fastcgi param PATH TRANSLATED  document root fastcgi script name

I had a similar problem  nginx was processing a page halfway then stopping  None of the solutions suggested here were working for me  I fixed it by changing nginx fastcgi buffering   fastcgi max temp file size 0   fastcgi buffer size 4K  fastcgi buffers 64 4k    After the changes my location block looked like   location     php        try files  uri  index php  404      fastcgi split path info       php             fastcgi pass 127 0 0 1 9000      fastcgi index index php      fastcgi param SCRIPT FILENAME  document root fastcgi script name      fastcgi max temp file size 0      fastcgi buffer size 4K      fastcgi buffers 64 4k      include fastcgi params      For details see https   www namhuy net 3120 fix-nginx-upstream-response-buffered-temporary-file-error html

In case anyone is having this issue but none of the above answers solve their problems  I was having this same issue and had the hardest time tracking it down since my config files were correct  my ngnix and php-fpm jobs were running fine  and there were no errors coming through any error logs   Dumb mistake but I never checked the Short Open Tag variable in my php ini file which was set to short open tag   Off  Since my php files were using  lt   instead of  lt  php  the pages were showing up blank  Short Open Tag should have been set to On in my case    Hope this helps someone

For reference  I am attaching my location block for catching files with the  php extension   location     php        include  path to fastcgi params      fastcgi pass  127 0 0 1 9000      fastcgi index index php      fastcgi param SCRIPT FILENAME  document root  fastcgi script name      Double-check the  path to fastcgi-params  and make sure that it is present and readable by the nginx user

Many users fall in this thread expecting to find a solution for blank pages being displayed while using nginx php-fpm  me being one of them  This is a recap of what I ended up doing after reading many of the answers here plus my own investigations  updated to php7 2    1  Open  etc php 7 2 fpm pool d www conf and check the value of parameter listen   listen    var run php php7 2-fpm sock   2  Parameter listen should match fastcgi pass parameter in your site configuration file  i e   etc nginx sites-enabled default    fastcgi pass unix  var run php php7 2-fpm sock    3  Check the file actually exists     file  var run php php7 2-fpm sock   var run php php7 2-fpm sock  socket   4  If it doesn t exist that means php7 2-fpm is not running  so you need to restart it     sudo  etc init d php7 2-fpm restart   ok   Restarting php7 2-fpm  via systemctl   php7 2-fpm service     With regard to the location section in  etc nginx sites-enabled default        pass PHP scripts to FastCGI server         location     php          include snippets fastcgi-php conf           With php-fpm  or other unix sockets         fastcgi pass unix  var run php php7 2-fpm sock         Check the file snippets fastcgi-php conf exists at location  etc nginx      file  etc nginx snippets fastcgi-php conf  etc nginx snippets fastcgi-php conf  ASCII text   This file contains a list of variable definitions required by php7 2-fpm  The variables are defined directly or through an include of a separated file    include fastcgi conf    This file is located at  etc nginx fastcgi conf and it looks like   fastcgi param  QUERY STRING        query string  fastcgi param  REQUEST METHOD      request method      fastcgi param  REDIRECT STATUS    200    nginx includes two possible parameter files  fastcgi params and fastcgi conf  The difference between both is the definition of variable SCRIPT FILENAME     diff fastcgi params fastcgi conf  1a2  gt  fastcgi param  SCRIPT FILENAME     document root fastcgi script name    To make a long story short  fastcgi conf should always work  If for some reason you re set up is using fastcgi params  you should define SCRIPT FILENAME   location     php      include snippets fastcgi-php conf       With php-fpm  or other unix sockets     fastcgi pass unix  var run php php7 2-fpm sock     fastcgi param  SCRIPT FILENAME     document root fastcgi script name      Now reload nginx configuration     sudo nginx -s reload   And check a php file is displayed correctly  For instance    var www html test php   lt pre gt  lt  php var export   SERVER   gt  lt  pre gt    Where  var www html is the path to the document root   If despite all that  you re still seeing a blank file  make sure your php ini has short open tag enabled  if you re testing a PHP page with short tags

The reason this problem occurs is because the fastcgi configurations in nginx do not function as required and in place or processing  they respond as html data  There are two possible ways in which you can configure your nginx to avoid this problem    Method 1          location     php                fastcgi split path info       php                       With php5-fpm              fastcgi pass unix  run php5-fpm sock              fastcgi index index php              include fastcgi conf         Method 2     location     php            fastcgi split path info       php                 include snippets fastcgi-php conf            With php5-fpm          fastcgi pass unix  var run php5-fpm sock          include fastcgi params       Both the methods would work properly  you can go ahead and take any one of them  They almost perform the same operations with a very few difference
