I have multiple sites in Alfresco, uploader plus is working fine for other sites except one, throws an exception and error pop up says "operation failure".
uploader plus is working fine for the individual folders. but issue comes when we are applying this to the documentLibrary folder of a particular website.
Also not able to upload any document in that particular site, giving internal server 500 error.
Please refer attached screen shots for more details.
Let me know if you have any resolution/workaround for this issue.
Thanks in Advance.enter image description here

"allowedTypes": []
}
}
</#escape>
