Everytime I update Piwik from master, via uploading the new files using ftp, I got the information on the system testing site in the config backend, that data integrity is damaged.
Looking in the details there are about 100files mentioned with different file sizes.
Reuploading everything doesn't change anything
Updating piwik to a new (beta) version via the "update manger"
everything is fine.
=> is it only a "cosmetic" issue or may this cause / be the reason for some unnecessary bugs/bugreports or un-similar behaviour on different installations?
And if you have updated to a "pre" new version from master, its not possible to (re-)update using the update manager if the new version is official available. Maybe a "reinstall" would be helpfull here...
last tested with updating from master 8.12.13 12:00 Europe
You can delete the file config/manifest.ini.php to hide message from System check page
=> so it is only a "cosmetic" problem?
It's unusual use case to have both Git setup and also have the manifest file, so deleting the manifest file is good enough workaround the message.
