If your file fail to upload, check your dolibar/documents/dolibarr.log It will give you an idea of what is wrong. In my case, I’d moved servers and neglected to install clamav, so the problem was dolibar could not invoke clamav.
I really like this feature. I keep my documents directory out of the webroot and keep my webroot locked down as a user other then apache when in production. The documents directory is writable, but is out of the webroot and also dolibarr is scanning everything I upload.
