Login forms error - Legacy context API

Hello dear friends,
I get the following error, and the text and buttons are not rendered properly. Any advice will be much appreciated.
Thank you

index.js:1 Warning: Legacy context API has been detected within a strict-mode tree.

The old API will be supported in all 16.x releases, but applications using it should migrate to the new version.
