I have nothing extraordinary in my web.config. However, I did add some new keys according to Kentico recommendations.
<add key="CMSUseAutomaticScheduler" value="true" />
<add key="CMSRenewSessionAuthChange" value="true" />
I'll take a look at these on Monday as I don't want to ammend the web.config on a Friday afternoon.
