Technote Details :: Maximum file size
Issue
When trying to submit data to a form, including a file that is uploaded from the loical hard-drive, I get an error message saying: "File upload error: File size must be less than xxx kB".
Reason
This happens because the file that is uploaded is bigger than the maximum size allowed. The maximum size is specified in the File Upload trigger configuration. If using PHP, there is another setting in the php.ini file concerning the maximum size for uploaded file.
Solution
Only upload files smaller than the maximum limit, or edit the File Upload server behavior and increase the maximum allowed file size.
If the behavior still persists, you might need to change the maximum allowed size for uploaded files from the php.ini configuration file.
