When I restart my portal from Host --> Host settings all my portals defined on my portal system lose their setting to their logo file in Admin --> Site settings????? Result: The logo file is missing on all portals...
It's a big problem.....it's not possible to edit hundreds of portals every time you need to restart the application.
Is their any solution?
