U10 site using uSkinned (U10.6.1, uskinned 3.0.5). All the blog item pages and also category listing pages are returning a 404. This was definitely working until it went live last week but we can't say for sure if it changed then or just today when the client went to put in a new blog item and realised it was broken. (The existing items were carried over from an old site) We have used this system many times, same versions, and never came across this before. Things we've tried: - unpublishing and publishing pages and sections - took all 301 rules and then all IIS redirect rules - restarted site and app pool several times - checked the template, to the extent of taking everything out of it in case there was an error in the code but it still just 404s - Refreshed all the Caches in Settings > Published Status It's working locally on my machine, I republished in Visual Studio and uploaded all the DLLs again and no joy. The listing page works, the blog items appear in search results. Nothing in the logs Does anyone have any ideas of anything else we could try? Thanks
