If you mean that people can see a listing of the directories. Than you may have an error in your .htaccess.

It should be disabled: see https://github.com/Elgg/Elgg/blob/1598cc34dfec71bff969563c2c7b070e616bb2a5/install/config/htaccess.dist#L6-L7

Indeed. Fixed now. Thanks.

Use this version https://github.com/hypeJunction/Elgg3-hypeDropzone/archive/refs/tags/6.0.0.zip

I tried it, but unfortunately it does not fix the problem. Do I need to edit any file in files plugin ?

Just tested it and this plugin works very well as is without any modifications.

• Deactivate the existing hypeDropzone plugin.
• Remove this folder /mod/hypeDropzone from your server.
• Run 'Flush the caches'.
• Download https://github.com/hypeJunction/Elgg3-hypeDropzone/archive/refs/tags/6.0.0.zip and unzip it to /mod/hypeDropzone
• Activate plugin
• Go to Files and try to Upload a file

It's been some years that I had some incomplete entities, back in the days of some Elgg 1.x. I guess it was due to some server glitches back then. The DbValidator plugin helped to sort out the issue.

The version to be fount in the github repo you've linked should still work on Elgg 2.x (probably NOT 3.x or newer anymore). The plugin has two options "validate" or "repair". You can try a validate run first. If it works without (php) errors the repair option probably works, too. In any case, backup your database before doing a repair run!!

Thanks iionly!

I tried the dbvalidator plugin on Elgg 2.x site and it works like a charm.
