Uploading images for forum posts (/userfiles/*)

Hi

I let the users of my website upload images so they can add pictures to their forum posts. Uploading a picture works, but the newly created file in the userfiles subfolder of the site has weird permissions. It seems that MojoPortal somehow specifies permissions to use when creating the file. In my case this means that the IIS account has no permission to access the uploaded file.

The userfiles folder itself has correct permissions and permission inheritance to child folders is enabled.

When I manually create a new subfolder and file in the userfiles folder IIS can access the file. The problem occurs only when uploading/creating files via "File Browser".

IIS uses it's own account and a special app pool for this site.

Cheers,
Simon

Make sure the App_Data folder is writable by the web process. If it is not then the temporary location for uploads is under Windows/temp and this causes funky permissions on the files. If App_Data is writable it should write there for temporary files and then permissions should be ok after the file is moved.

Also make sure on your folder permissions that is is configured for permissions to propagate to child objects, if not then uploaded files may not inherit the         correct permissions from the folder.

Hope it helps,

Joe

Great, that did the job. It would be nice if the Security Advisor would warn about this or if MojoPortal broke completely if the permissions aren't set correctly.

Thanks for the help and have a nice weekend!
