In admin it tells me that the "Rebranding WP Multisite" plugins need to be upgraded, that the latest version is 1.08.
I've downloaded the latest plugin folders and reinstalled but it still tells me the same thing.
Inside the changelog.txt files of the respective folders that I just downloaded, it tells me
Admin Footer Text - 1.0.6
Admin Help Content - 1.0.3
Login Image - 1.0.6
Remove Permalinks Menu Item - 1.0.2
Remove WP Dashboard Widgets 1..0.2
What should the latest versions be? If these aren't correct, you need to update the download link.
