I\'m running WP 3.0.1 on a shared host using PHP5. I\'m having issues uploading files that are a little larger via the media uploader in the admin section of WP.

I had the same issue whenever I tried to upload media, except I got the "HTTP Error" on files larger than 124Kb! WP 3.3.1, PHP 5.2.
I called my host and they upped memory to 64M (also changed this in wp-config) and upload_limit to 8 MB (default was 2 MB). This didn't work so I resorted to almost everything else, from tampering with the .htaccess to reinstalling WP to installing a fresh WP on another server, but everything pointed to a server issue. I called the host again and spoke to another technician who increased the allowed HTTP Request Length setting.
