When i publish items in sitecore ( Sitecore 8 Update 2 ) i noticed that the presentation details aren't being published. At first this didn't happen a lot but now it's becoming a real problem.
I used to have a fallback plan where i would fully delete the items in the web database and then a publish would work fine. But now even when i delete the items from the web database only the item itself is published. There is no error or message.
( I just tried to add the presentation details to the web item itself, saved it and looked at it again. But the new presentation details were gone )
Does anyone know what could cause this ?
I experienced the exact same problem and it turned out to be due to the renderings (and the containing folder) used by the page having been created in the wrong language.
If you try to a) publish in all available languages, or b) ensure that your rendering definition items (and all ancestors) are in the correct language, this could fix your issue.
