So after upgrading, our site works fine. All the content and images are in place. And our images uploaded by File Manager are still in place in the server in the same location. This location is also intact in the File Upload Preferences.
I see a notice in the File Manager now to “sync your directories.” Is this the answer to my problem, to getting the files to show up in File Manager again? Anything I should know or be careful about before performing this sync? Thank you.
