Hello,

We have a customer hosting with us using DNN on their site. When trying to view their forums they are receiving an error about being unable to access temporary files. What user account needs permissions for this to work properly and is there a way to change the location of the temporary files? I'm not sure I'm comfortable with temporary files being stored on the same drive as the OS due to security reasons. Below is the full error message/stack trace:
