Why is fmelfinder not loading images?

Question

symfony

Hello! I had a problem setting up the fmelfinder bundle. Most likely I did something wrong. Here is the config.yaml

# FMElfinder Configuration
fm_elfinder:
    locale: %locale%
    editor: tinymce4
    fullscreen: true
    include_assets: true
    compression: false
    connector:
        debug: false
        roots:      
            uploads:
                driver: LocalFileSystem
                path: uploads
                upload_allow: ['all']
                upload_deny:  ['']
                upload_max_size: 5M

This bundle works with tinymce

# FMElfinder Configuration
fm_elfinder:
    locale: %locale%
    editor: tinymce4
    fullscreen: true
    include_assets: true
    compression: false
    connector:
        debug: false
        roots:      
            uploads:
                driver: LocalFileSystem
                path: uploads
                upload_allow: ['all']
                upload_deny:  ['']
                upload_max_size: 5M

The problem itself occurs when you try to open the bootloader. A small pop-up window displays the following error:

Invalid backend configuration.
Readable volumes not available.

What could be the problem and how can it be solved?

Answer 1

The problem was due to the fact that I did not create the uploads directory, which I refer to in the config. It was also necessary to change the rights of the directory, otherwise all the buttons would be disabled, and nothing could be loaded.
