I updated my instance yesterday and Check the new profile directory but there is Some issue with it page. I am adding image of Page and Console warning it something with manifest.json File
It looks like you haven’t run
rake assets:precompile so missing latest style updates.
Just Updated to Version 2.7.0 Still the same issue Take a look
It has been solved. The problem was single CPU the process got terminated because of load. The workaround is stop mastodon services and after that Start compiling.
