Hi there,
Just to notify the team. When performing an upgrade of my community (self hosted) from 4.5x to 4.7.0, the automatic upgrade failed and it prompted me to upgrade manually. I followed the installation guide to complete the manual upgrade, downloading the 4.7 installation files from my client area and uploading my files over FTP successfully. However when I visited admin/upgrade I was prompted that there was an issue with the following file not being correct:
[root]/community/applications/core/modules/admin/system/upgrade.php
It stated that the file was not for the correct version, or the permissions were not correct. However after double checking permissions, redownloading and reuploading this file, I could see the error was with the file actually provided for download in the client area.
Thankfully an auto install worked correctly on my staging site and I could then see a difference in the files: staging site: 56016 bytes downloaded file: 56116 bytes
So after copying that file from my staging site over, the upgrade completed successfully.
Just want to avoid other users facing the same issue.
