Hi, I have a weird issue with which I've been dealing for the last 4 hours I really don't know what to do at this point, the problem is that everytime I open an aspx page from a dotnetnuke module the session expires, the page is open in a new window using window.open, I'm also using telerik RadWindowManager. When I close the window and return to the portal and click a link it redirects me to the login page. The aspx pages are stored on the same folder as the module, any help would be greatly appreaciated, thanks.

That was the problem, thank you so much! I wish I would had posted on the forum earlier.
