Activity app launches Update Needed page

Hi,

I recently upgraded from 9.0.53 to 10.0.1 and today I went in the apps menu and activated the activity app. From that point I get on the browser the Update Needed page:

Update needed

Please use the command line updater because you have a big instance.

For help, see the documentation.

Anybody knows what caused this and how to solve it?

Thanks!

Running the update (as suggested) should solve this. So on the command line run:

./occ upgrade

this command is not working for me
[root@localhost public_html]# ./occ upgrade
-bash: ./occ: Permission denied
