Hi Chris,
Usually there is a button somewhere in the hosting control panel to recycle the app. Touching the Web.config by downloading it and uploading it again should also recycle the app most of the time.
None of the errors you posted previously are stoping the site fromk running so we need to find out what the real error is.
Please look for this in Web.config:
<customErrors mode="RemoteOnly" defaultRedirect="Error.htm">
and change it to:
<customErrors mode="Off" defaultRedirect="Error.htm">
That should get you past the generic .NET error page and give more error info.
Please start a new thread and post the error.
Best,
Joe
