[lufog]

To fix run: php bin\gpm update -y.

[paulhibbitts]

Thanks very much @lufog but when I try that I get a nothing to update message and still no luck with the Pages Admin panel.

[mahagr]

@paulhibbitts you can fix this by running composer update --no-dev in the root folder of the installation. If you don't have composer installed, grav has one built into it as well.

[paulhibbitts]

Thanks @mahagr but still getting that error message (I cleared cache too). Maybe I need to wait for the next RC to test the update process?

[mahagr]

Oh, you also need to get the latest Grav source.

[paulhibbitts]

Thanks @mahagr , for now I will just download a fresh R5 and copy my needed pages/themes/plugins/etc
