UPDATE: You should always be careful if you use "rsync -r" on a directory with "--exclude=files", because it will exclude the "dashboard/controller/files"-dir as well, which is not the best choice if you want to load the file manager. ;) (Use "--exclude=/files" instead). ;) Problem solved.

Hey c5-folks!

I'm testing a deployment concept right now. I stumbled across an error that the file manager does not load correctly and that there is only a blank page under the file manager tabs.

How can I debug this? There are no report logs or errors visible in my php-error-log. Permission are 777 and the apache-user (www-data) owns it.

What I did was simply coping the files and packages folder from a live/production server to a staging server. And I also copied the db from the production server. I thought maybe this is a cache issue, but clearing the cache did not help.

Help much appreciated!

Thanks!
