"The module was not installed"

I have a copy of my Backlight website on my local Synology server. When I installed Backlight 5, I copied the backlight folder from the server on the web to the local server. I have done this before with no issues. Everything works fine except when I try to update modules on the local machine. I get the message “The module was not installed.” Can you point me to a log file that might have some information I can use to figure out why this has started happening?

Hi @kolohe280, it could be a permissions issue. Are you able to publish photos?
The log files for your web server may shed some light on it.
