Hi.

When I try to read the “OpenProject upgrade guide”,(https://www.openproject.org/open-source/packaged-installation/packaged-installation-upgrade-guide/) I get the following text (multiple browsers tested):

<!DOCTYPE html>

….
Please fix it.
Thank you.

Hi Matija,

We’ve noticed this as well and are working on fixing this issue. In the meantime you can access the upgrade guide here
