Hi,

 I have DNN4.3.5 site running well, only problem is:

after several minutes idle, when I refresh the DNN4.3.5 site, localhost/DNN435source always redirect to

I believe it is web.config problem, I double checked, there is <addkey="InstallationDate"value="9/22/2006"/>  in web.config,
Maybe I changed somewhere in web.config file, so DNN could not read the installed flag from web.config or from database, so when I open a new DNN site, it alway try to install.
anyone could help?
Here is the Error:
Server Error in '/DNN435source' Application.
