File upload error

It wouldn’t let a colleague upload a 8 meg PDF file. It complained about file size, even when she tried a 2 meg file. Any ideas?

Often there are limits to the size of a file that can be uploaded in the php.ini file. Check to see if there's a php.ini file in the omeka directory (or in directories above it), and look for a line that looks like
upload_max_filesize = 2M ; Maximum allowed size for uploaded files

(In mine, it's around line 260). Increasing that might do the trick.
