I have an installation of the YAF v2.2.2 running on a Windows Server 2008 (not R2) box that, according to the specs, meets all the pre-requisites (.NET v4.5.1, SQL server 2008, IIS7). Are there any other requirements that

However, no matter what I try, I am completely unable to upload any files as administrator or a normal user. I have checked the access masks for the user roles and forums and the users *should* have upload/download rights.

The database is set to hold the files in an upload table and I have tried going back to a file system approach but that does make any difference.

I have also tried reinstalling YAF via different methods (manually from the zip file, using the Web Platform Installer) but the result is always the same. I know it is something to do with my server as the functionality works on this forum! The odd thing is that I can create albums and upload pictures to them without a problem.

Any suggestions on what else to look at on the server?

Thanks for your help.

That's the odd thing about it - nothing in the Event Log.

This happens with both Firefox and IE, on Windows 7 and 10 - nothing

Using Firefox with the Web Console open, when I "drop" a file or try to attach a file from the popup, I get a "TypeError: r is undefined" entry with the following on the right hand side

"/Scripts/jquery.fileupload.comb.min.js :1:45877

I have tried uploading file types that are registered in the admin pages and the option for filetypes is set to "Allow" - thinking it was a problem with the changes to the filetypes I made, I also made a fresh install to the same server but had exactly the same issue.

Would appreciate your advice.

Thank you

Sorry to chase, but any thoughts on what is going wrong on me?

Cheers
