Hi UC,
I'm new to Silverstripe, the uploadify module can upload the file to the folder but cannot attach it. I can see your uploaded file is in the
right folder, and I can attach it afterwards, but it fails to attach the file at the time you upload it.
It seems many others has the same question, I already add the code ContentNegotiator::disable(); to the uploadify/config.php and <IfModule mod_security.c>
SecFilterEngine Off
</IfModule>
to mysite/.htaccess
but none of them solve the problem....
many thanks
