idebr CreditAttribution: idebr commentedI fixed this by saving the 'Manage fields' display again for a node type, eg. basic page.

pythagory CreditAttribution: pythagory commentedI'm not able to reproduce this problem on a fresh installation of 8.0.x-dev. Can you elaborate on your setup? Was this a fresh install or had you already configured/added modules/etc? If not a new installation, had you pulled in code changes from upstream (git pull) after installing?
Comment #4
a.milkovskyI can confirm the problem. For me it appeared when I updated to the latest dev. Configuration was exported using beta-6.

subhojit777@a.milkovsky Then I think you should you re-open this issue telling in detail what error you were getting, and how it got removed. You can change issue title and body if you need.

Gen.Chu CreditAttribution: Gen.Chu commentedI have the very same problem with the config page (/admin/config). I updated from beta 6 to beta 7 and imported my configs. I don't have the problem on a fresh Beta 7 install. I did resave blocks and my content types fields, doesn't seem to make any difference.
