Regarding the Developer module, it's clear that the installation was not completed correctly. I suspect there may be an issue with folder and file permissions. You will likely need to fix the permissions and then uninstall and reinstall the module manually via SSH or PHPMyAdmin, directly through the database.

f you need to set the correct permissions for UNA CMS, run this command:

Save as a file if you need further help to restore UNA permissions set_permissions.sh

#!/bin/bash
# Filename: set_permissions.sh

# Move into the 'una' directory
cd una || { echo "Directory 'una' not found!"; exit 1; }

# Change the owner of all files and folders to 'www-data'
sudo chown -R www-data:www-data .

# Set permissions for all directories to 755:
# 7 = read (4) + write (2) + execute (1) for the owner
# 5 = read (4) + execute (1) for the group
# 5 = read (4) + execute (1) for others
sudo find ./ -type d -exec chmod 755 {} \;

# Set permissions for all files to 644:
# 6 = read (4) + write (2) for the owner
# 4 = read (4) for the group
# 4 = read (4) for others
sudo find ./ -type f -exec chmod 644 {} \;

# Give execute permission to ffmpeg.exe (since it's an executable)
sudo chmod +x ./plugins/ffmpeg/ffmpeg.exe

# Go back to the previous directory
cd ..

# Set this script's owner to 'root' and permissions to 755
# If you want, replace 'root' below with your SSH username
sudo chown root:root set_permissions.sh
sudo chmod +x set_permissions.sh

# Display confirmation message
echo "Permissions successfully set. Script permissions preserved."

How to use:

1. Create the file:

vim set_permissions.sh

1. Press i to enter Insert mode.
2. Paste the code from above.
3. Save and close:

• Press ESC
• Type :wq
• Press Enter

Final steps:

• Make the script executable:

sudo chmod +x set_permissions.sh

• Run it anytime to restore your file and folder permissions:

./set_permissions.sh

What this script does:

• Sets the correct ownership (www-data:www-data) and permissions for your una/ project.
• Makes sure ffmpeg.exe stays executable.
• Preserves its own permissions as root:root with 755, so it’s always ready to use safely.

Happy coding!
