problem with uploading large files

[eluser]ebuoe[/eluser]
hello i've been unable to upload files larger than 1mb ... n i have these settings in my php.ini
post_max_size = 100M
upload_max_filesize = 100M

and i even increased the max_execution_time and max_input_time
it shows me this message "The file could not be written to disk"

what could be the problem any help would be appreciated

Be sure that you're not setting xss_clean on file uploads, other than that the only time that error message is shown is when PHP produces UPLOAD_ERR_CANT_WRITE, which I suspect is thrown because of a permissions problem.

Check your php.ini file thats were your file upload settings are defined!

Code:

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 256M
