I just upgrade to DNN9 for a website with many child portals. EVerything seemed fine first but I notice whenever I update any page setting, move or add a page, the menu will loose the child directory and all page will link to the main portal.
For example, on dnndev.me/child, if I add a page called test, the link in the menu will go to dnndev.me/test.aspx instead of dnndev.me/child/test.aspx
Restarting the application and clearing cache fixes it until the next change.
Is this a knwon issue?
