Recently I am having issues when attempting to add images to a wordpress site to the media gallery when they get much over about 0.75 MB in size.

If i use the standard multi-file uploader i get a generic HTTP Error and nothing shown in the error logs of my server. If i use the browser uploader, i get a 500 server error, and the server error logs then return the following errors:

[Thu Sep 25 18:40:06 2014] [error] [client 107.188.184.102] , referer: http://www.the-tribunal.org/wp-admin/media-new.php

I am using php 5.4 single php.ini with the following extensions enabled:
Http
Imagick
Magick Wand
Mail Parse
OAuth
OCI8
Upload Progress
IonCube
SourceGuardian

Currently i have reset all file/folder permissions correctly, reinstalled php.ini, increased timeout and upload settings via php.ini, deactivated all plugins and using only the default twenty fourteen theme.

This happens with my current install, or even with a new default install using a different db, db user, wp core files, twenty fourteen, and no plugins enabled.

I contacted my host who is not able to determine the issue. Any help or ideas would be wonderful!
