Is that setting a custom built plugin? Might be that you forgot to include some aspx in project that is deployed to DXC? Might be that you have a "localhost" reference somewhere in it?
Yeah custom code from this link https://world.episerver.com/blogs/joe-mayberry/dates/2019/2/working-with-the-local-object-cache/. Not added any localhost reference witjin codebase.
Hmm sounds like the postback to the action method isn't able to map to correct method for some reason. I'm not familiar with that plugin.
Might be the related to the
Redirect within web.release.config was causing this page not found error. We are able to use the plugin now.
If any of the link within Episerver Admin -> Tools -> Setting item loads the page just fine and if we select any value and click on button within page it gives "page not found" error in integration DXC environment and works just fine in local environment.
Where we can get what is that causing error for this in Episerver Admin section?
