I'm running (or better "attempting" to run) my site built with mojoPortal in a hosted environment that does not allow access to C:\Windows\Temp.  I can understand why, and I attempted to resolve (by adding tempDirectory = "somewhere in my file structure" to the compilation tag in web.config like this:

<compilation tempDirectory="d:\hosting\member\xxx\TEMP" debug="false" defaultLanguage="C#">

for some reason, I'm still getting errors when the site is loading indicating that it is still trying to utilize C:\Windows\Temp.  Am I missing something???

frustrated, Daniel

Thanks.  I removed the change to web.config.  Here is the error (the name of the file changes after refreshing a few times):

Server Error in '/' Application.

Thanks, Joe!  The site appears to be working now.  It's done this before and then reverted to the errors below after a few minutes, so I'm figuratively holding my breath at this point (but it's been working through 10 minutes of steady refreshes).  

I'll send an update in an hour or so if it is still up.  

Thanks, again!  Your beer is on the way!  

Daniel
