# Upload HTTP Error (detailed)

 * Hello. I have two wordpress sites running on Debian 8 with MariaDB, Apache MPM-
   Worker multithreaded setup forwarding php parsing to fastcgi. All programs are
   up-to-date based on Debian repos.
 * My memory limits as defined in all the php.ini files are 256MB, squashing the
   typical recommendation to bump up to 128MB. I just verified this with a phpinfo
   while writing this. Also these if they help…
    Server API CGI/FastCGI ZenD Opcache
   Free memory 12806248
 * I checked for my POST message in the logs for attempting to upload and found 
   this by itself:
 * [01/Oct/2015:18:23:49 +0000] “POST /wp-admin/admin-ajax.php HTTP/1.1” 200 751“
   [http://duvrazh.net/wp-admin/upload.php&#8221](http://duvrazh.net/wp-admin/upload.php&#8221);“
   Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/
   45.0.2454.101 Safari/537.36”
 * It’s not theme specific, these two sites use two different themes and have a 
   completely different set of plugins installed, with the exception of cloudflare’s
   proprietary plugin for enabling development mode.
 * I’ve verified upload folder permissions are 755 with ls
    drwxr-xr-x 5 www-data
   www-data 4.0K Oct 1 14:50 uploads
 * I am open to suggestions… This error is all over the internet. Hundreds of posts,
   search results, no solutions have worked. I’ve added security bypasses for uploading
   to .htaccess, I’ve increased all memory allocations to a quarter gig, I even 
   made the upload directory 777 for a moment just to test. I’m at a loss. Any assistance
   would be greatly appreciated.

 * Sorry if I’m missing something, but what is the exact error message that you’re
   seeing?
 * Also, what is the size of the file you’re trying to upload and what are the values
   in your phpinfo() page for `upload_max_filesize` and `post_max_size`?

 * This link is a for a screenshot of the error.
    [http://pasteboard.co/13YotXlJ.png](http://pasteboard.co/13YotXlJ.png)
    - upload_max_filesize 2M
    - post_max_size 8M
 * The item I attempted to upload for that screenshot has the following properties:
    - Size – 177 KB (181,808 bytes)
    - Size on disk – 180 KB (184,320 bytes)
    - Height – 1920
    - Width – 1080

 * shoot, I was afraid that was the error message since it seems to be a catch-all
   error that isn’t easy to debug.
 * A few ideas:
 * – Do you get the same error if you attempt to upload a pdf? If no, looking at
   your phpinfo() page again, is GD or Imagick [installed and enabled](http://www.inmotionhosting.com/support/website/software/is-gd-library-installed-on-the-server)?
 * – Do you get the same error if you use the “browser uploader” (/wp-admin/media-
   new.php?browser-uploader) as well?
 * – if you recently installed or upgraded WordPress it might be worth a try to 
   re-install the WordPress core files (everything except wp-content) in case there
   was a problem with the install/upgrade.
 * – Does the response from the upload’s ajax request (use your browser’s developer
   tools i.e. [chrome’s](https://developers.google.com/web/tools/profile-performance/network-performance/resource-loading#network-panel-overview))
   give a clue of what is causing the error?

 * Aight here goes.
    - PDF Upload – Failed – same error on page
    - PDF Upload – Developer Tools Error – [http://pasteboard.co/14J27HFN.png](http://pasteboard.co/14J27HFN.png)
    - I’ve already reinstalled wordpress – I’m going to rule this out
    - GD – [http://pasteboard.co/14JdcDy5.png](http://pasteboard.co/14JdcDy5.png)
    - ImageMagick – [http://pasteboard.co/14JgQ5Cw.png](http://pasteboard.co/14JgQ5Cw.png)
 * I am a system admin by day – but not an Apache admin by any means. I’m looking
   at that browser error… Found it in the combined log searching 500.

 * I use Sumo to collect and search logs so I did a +/- 1 minute – [http://pastebin.com/hNd3MKh1](http://pastebin.com/hNd3MKh1)–
   nothing stands out of these at me. Do GD and ImageMagick conflict when jpg support
   is enabled on both modules?
 * I know this goes against best practices but I’m going to go ahead and leave my
   phpinfo() in place – you’ll be able to take a look if it will assist. [http://www.duvrazh.net/phpinfo.php](http://www.duvrazh.net/phpinfo.php)

 * Thank you for the additional information, to answer your question
 *     ```
       Do GD and ImageMagick conflict when jpg support is enabled on both modules?
       ```
   
 * – My understanding is that WordPress will test for a set of ImageMagick functions
   it needs and if they’re not present then use GD. Everything you’re running is
   new enough that I don’t see that as being the cause of the problem.
 * If you haven’t already, you can try disabling all plugins and if uploading then
   works start enabling them one by one to see which one is causing the conflict.
 * Next, I’d recommend you add the following code to the top of your wp-config.php
   file, try uploading a couple more times, and then examine wp-content/debug.log
   to see if WordPress logs any errors to that file:
 *     ```
       define( 'WP_DEBUG', true );
       define( 'WP_DEBUG_LOG', true );
       ```
   
 * Finally if that doesn’t work, you can also try to debug the upload script itself(
   wp-admin/async-upload.php) by adding code the following, trying an upload, and
   then checking wp-content/debug.log to see if any errors are being thrown:
 *     ```
       $log = print_r( array(
       	'file'        => __FILE__ . 'on line ' . __LINE__,
       	'request' => $_REQUEST,
       	'foo'        => $bar
       ), true );
       error_log( $log );
       ```

 * That’s a step up on the involvement required since I don’t have those logs being
   collected by Sumo. I’ll run those tests once I automated turning on debug mode
   with a bash script.
 * Thanks for the next step. I’ll post results this afternoon.

 * All that work for nothing. I made a couple extra files in ~ and made some aliases
   to put a site into debug and you know what?
 *  0 -rw-r–r– 1 www-data www-data 0 Oct 2 18:04 debug.log
 * I had to touch the file… one didn’t create on it’s own. Either no errors are 
   being thrown or the debug flag isn’t doing anything. My aliases modified both
   files btw.
 * I did a find debug.log from the site’s root directory but no joy. I’m thoroughly
   confused. These were all fantastic suggestions so far, I was certain this would
   unearth some kind of a clue.

 * That is strange and I’m not sure what else I could suggest to try to narrow down
   the cause. Sorry I couldn’t be of more help, but best of luck.

 * I figured it out. If you’ve configured your server, Debian Jessie in my case,
   to pipe php into FastCGI for multithreaded Nginx-esque speed, there is a FastCGI
   default value of 128kb for max post length.
 * This is insanely under-documented. Add the FcgidMaxRequestLen and desired value
   in **bytes** to your fastcgi.conf in /etc/apache2/mods-available like the following.
 *     ```
       <IfModule mod_fcgid.c>
         FcgidMaxRequestLen 26214400
         FcgidConnectTimeout 60
       </IfModule>
       ```
   
 * 26214400 = 25 MB
    8388608 = 8 MB 1048576 = 1 MB (for easy multiplication)
