Can't Upload files

[rppf]

I can't upload files. I'm using Alfresco 4.2.c. There's nothing wrong recorded in catalina.out. All I have is an error message from Chrome Browser saying

dnd-upload_bf7b4bcf94c5e6bf856587ffa42654d8.js:1 Uncaught TypeError: this._addFiles is not a function

I already allowed Flashplayer to run on the website.

Any solutions? I'm using Alfresco Community 4.2.c

It's a strange problem, as dndUpload is a core component from share. It seems there's some library missing. Do you have any customizations in your installation? Can you upload files using the Upload button, or is it giving the same error?

[rppf]

Yeah there's some slight modifications.

Check whether you can open yui-common.js from inside the browser (f-12, ctrl-o, type yui).

Check whether this file is present in your installation. It should be found in <install-dir>\tomcat\webapps\share\js\yui-common.js.

[rppf]

Yup. That certain file is present.
