Hi,
I have a new installation of Piwigo. I am trying to use the FTP/synchronize feature.  I didn't get an error when I did the sync. After seeing that the images are broken, I went to Photos - Batch Manager and tried to generate multiple size images. When I do this, I get a message "photos cannot be regenerated." 

I looked for the log file in _data/tmp/i.log but this tmp folder does not exist.  I did open the log file in _data/logs, and I see some errors such as:
[2022-04-07 4:50:15]    [ERROR]    [i.php]    404 Source not found
  url: '/gallery/i.php?/galleries/Egypt_1992/TA15-08-sq.jpg'

I can confirm that the source file that I uploaded via ftp to /gallery/galleries/Egypt_1992 do exist and all the files have the same permissions and the folder has 755 permissions.

I also deleted some of the offending photos and re-synced the ftp. The photos were removed. I then uploaded the same files again, and then did the synchronize.  The same problem is there.
