Hi,

when i am trying to upload a large file (45mb) with the attachment option of an item i get back following error

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Additionally, when i am trying to select this file from the server it gets added but it is not available at the frontend although i can download it in the backend.
This only happens with files which are greater then 20MB. Any idea what could be the cause?

Here are my php Settings
Maximum Post Size: 300M
Upload Maximum File Size: 500M
Maximum Execution Time 300
Maximum Files to Upload 20
Maximum Input Time 60
Memory Limit 128M

Joomla 3.2.2, K2 2.6.8, PHP 5.4.14

Hi. What kind of file are you trying to upload? All these notices come from a core Joomla! file and probably have nothing to do with the upload. Also your PHP settings may affect this. You have set for example Maximum Execution Time 300. If your upload takes more time it will fail.
