# HTTP error

 * Hello,
 * When I try to upload PDFs, I get an “httperror” message on the right-hand pane
   and the document doesn’t show in the library until you close the media library
   and re-enter, and it’s also stopped generating thumbnails. Other media types,
   such as JPG and PNG work fine, but PDFs just won’t generate properly.
 * I’m not sure what info you’ll need in order to help me diagnose the issues we’re
   experiencing, but any help anyone’s able to give would be gratefully received
   🙂

 * Hi lennonrich
 * Thank you for your feedback.
 * I think HTTPerror problem is 90% in file size, RAM memory, and not failing Imagick
   library.
    Have you tested to upload smaller one? If it works, Increase values
   in php.ini, for example:
 * memory_limit = 64M
    upload_max_filesize = 64M post_max_size = 64M
 * And add the following code to wp-config.php:
 * define(‘WP_MEMORY_LIMIT’, ’64M’)
 * If your server has not enough memory, try uncheck “Customize Generated Image 
   properties” in the options setting page of the plugin.

 * Hello,
 * Firstly, many thanks for your help so far.
 * Tried to upload a 5kb PDF and still getting the error, even after applying those
   fixes. The PHP config is:
 *     ```
       memory_limit = 256M
       upload_max_filesize = 32M
       post_max_size = 32M
       ```
   
 * For reference, this is the error we’re getting:

 * This is the size of the PDF file we’re trying to update:
    [Hosted on Imgur](https://i.imgur.com/jCfDPrz.png)
 * And if you close the media browser and then re-open it, the file is there, albeit
   without a thumbnail:

 * Could this be a permissions issue on the host?
 * Thanks in advance!

 * Thanks for giving it a try!
 * Can you check the wp-content/debug.log file for errors?
    If you don’t have it,
   please add the following to your site’s wp-config.php file.
 *     ```
       define('WP_DEBUG', true);
       if ( WP_DEBUG ) {
       	define('WP_DEBUG_LOG', true);
       	define('WP_DEBUG_DISPLAY', false);
       	@ini_set('display_errors',0);
       }
       ```
   
 * And let me know what you findings.

 * Hiya,
 * So this is the error message:
 * [12-Apr-2016 08:11:27 UTC] PHP Fatal error: Call to undefined method Imagick::
   setImageAlphaChannel() in /home/bathandnortheast/public_html/assets/plugins/pdf-
   image-generator/pdf-image-generator.php on line 276
 * I then tried it with a different PDF, just to test:
    [12-Apr-2016 08:17:01 UTC]
   PHP Fatal error: Call to undefined method Imagick::setImageAlphaChannel() in /
   home/bathandnortheast/public_html/assets/plugins/pdf-image-generator/pdf-image-
   generator.php on line 276
 * However, ImageMagick is definitely installed on the server:
    [Hosted on Imgur](http://i.imgur.com/UYh3TU4.png)
 * Could it be because our wp-content directory has been renamed ‘assets’ for security?
 * Many thanks again for your assistance!

 * Thanks for reporting, it really helps!
 * setImageAlphaChannel() requires imageMagick 6.3.8 or newer.
    I think your ImageMagick
   version is older than the required minimum.
 * I uploaded the Development version 1.4.0b.
    This version verify imageMagick version
   and separate process.

 * I couldn’t test it in my server because it is difficult to make the same environment
   with you.
    So, please test it and let me know whether it works.
 * Thank you!

 * Hiya,
 * Thanks for the update! Tried with the new version and tested with three different
   PDFs with no success:

 * Sorry, I forgot to notice that you need to re-activate the plugin after uploading.
   
   Could you try again?

 * Hiya,
 * Here’ what I did:
    - Deleted the existing plugin
    - Uploaded the new plugin
    - Deactivated the plugin
    - Reactivated the plugin
    - Went into Options, unchecked using custom dimensions and saved
    - Uploaded a PDF
 * Unfortunately it still fails, with the message:

   setImageAlphaChannel() in /home/bathandnortheast/public_html/assets/plugins/pdf-

 * Hmm. The result is different from what I was expecting.
 * Could you tell me what version is your imagick is?
 * Please paste in the functions.php.
 *     ```
       if ( is_user_logged_in () ){
       $v = Imagick::getVersion();
       preg_match('/ImageMagick ([0-9]+\.[0-9]+\.[0-9]+)/', $v['versionString'], $v);
       echo 'imagick version: '.$v[1];
       }

       if ( is_user_logged_in () ){
       $v = Imagick::getVersion();
       preg_match('/ImageMagick ([0-9]+\.[0-9]+\.[0-9]+)/', $v['versionString'], $v);

 * I’m sorry.
    That was just because of my miscoding. Try 1.4.1c.

 * **Edit:**Further, the media library’s stopped working in Grid View since this
   1.4.1c. It still works in List view, but not Grid view 🙁

    I fixed Strict standards errors.
 * Try 1.4.1d.

 * Hello,
 * No problems — I appreciate everything you’re doing 🙂
 * This is with 1.4.1d

 * **Media Library**
    When I load up the media library, the loading circle just 
   spins and spins and spins. If I press List View, it all loads in about a second.
   Click the Grid View button again, just nothing, spinning. This could be entirely
   coincidental, I just wanted to feed it back in case it helps 🙂

 * This PHP Strict Standards error is not because of the plugin. Because of the “
   Imagick::getVersion();” code you inserted one hour ago.
    Please remove the code
   from functions.php. Its role is finished.
 * **Media Library**
    I have no clue whether it’s because of HTTP error……
