Try to update it in the admin CP. System was not able to do it automatically. So, like recommended, I downloaded the pack and copied the content on the website. After, I clicked on the "Continue" button on the admin CP installation page but nothing happened. Tried another time all steps, without success. Finally, I decided to exit from admin CP and to log on the website. The top install notification bar was there saying that the 4.1.10 files were on the server, but they were not installed. I clicked on the installation button and everything went well then after.
