Project's REAME.md doesn't update

If I change my project’s README.md file remotely and then commit/push it to the gitlab.com server it doesn’t update the README.md on the project’s front page. Clearing the browser’s cache doesn’t give a help.

When I clone the project I can see that the README.md is correctly updated but it is the gitlab.com service who is not able to show me the latest version.

What could be the reason for this and how to fix it ?

The problem solved. The file was formatted incorrectly. gitlab.com service is working just fine.
