Hello Candice Zhou,

thanks! What's the .pdb file and why shouldn't I upload it?

I already tried the customErrors tag in my Web.config, but it had no effect:

• I added this to my Web.config (without an additional "error" tag:
  <customErrors mode="RemoteOnly" defaultRedirect="~/sys/Error.aspx"/>
• Then, I entered the hostname of my application with a non-existing subdirectory.
• This gave me the standard "not found" error page:

Server Error
