DNN 10.0.1 edit layout issues Started By willem We encountered some layout issues in DNN 10.1.0. Mostly in the edit/admin screens (module settings etc) The colors, tabs and layout are not as it was and we are using a theme that worked perfect in DNN 9.13.9 It's not alined like you want it to be default. Anyone else experienced the same issues in DNN 10.1.0 We now need to consider whether DNN 10 is ready for production or whether we should wait until all the childhood illnesses are resolved.

Experiencing Stability and Module Issues After Upgrading to DNN 9.13.4 Started By Mukesh Kushvaha Hello Community, We recently upgraded our DNN platform from version 9.11.0 to 9.13.4.

DNN 10 Relative Path Issue Started By MrKleen So we just upgraded from 9.13.7 to 10.00.00. Since the upgrade there are a few weird quirks we are running into with the relative path in certain areas. IN a few places it's looking at the server root instead of the site root. We did not encounter this with the older version. Our URL is set up like this 'www.devserver.com/ourdnnsite/', and since the upgrade there are a few admin pages where the relative path is wrong. If I go to 'Manage-->Themes' all of the image links are broken. Looking in ...	3	345	0	4/14/2025 4:31 PM by MrKleen
