Just wanted to let you know I have made same changes to the web config file that took care of the "view report" timeout.
Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out. still exists when I try to run reports from the control panel.
.
FYI the following steps are also suggested for Catalook:
Change this line in your web.config: <form>s name=".DOTNETNUKE" protection="All" cookieless="UseCookies" timeout="60" /> to <form>s name=".DOTNETNUKE" protection="All" cookieless="UseCookies" timeout="
600000" />
Add green marked parameter to the httpRuntime section of the web.config and change the red marked parameters:
maxRequestLength="2097151" requestLengthDiskThreshold="50000" executionTimeout="9000" />
Some Hosting providers also restrict the time on the server side. In this case please ask your hosting provider to remove the timeout restrictions. Here you can find more information: Timeout Error
