Thank you Nikolai.

It works well !

But the writing dropdown list remains visible and displays "private".

Is there a way to hide it?

(I clear the cache before each test I run.)

Forgot about saving...

Add a new event in your custom plugin:

elgg-plugin.php

'events' => [
        'fields' => [
            'object:page' => [
                \MyPlugin\Pages\FieldsHandler::class => ['priority' => 501],
            ],
        ],
],

Create a new file \mod\my_plugin\classes\MyPlugin\Pages\FieldsHandler.php

<?php

namespace MyPlugin\Pages;

class FieldsHandler {
    
    public function __invoke(\Elgg\Event $event): ?array {
        $result = $event->getValue();
        
        foreach ($result as $k => $field) {
            if (elgg_extract('name', $field) === 'write_access_id') {
                unset($result[$k]);
            }
        }
        
        $result = array_values($result);
        
        return $result;
    }
}

Note: your custom plugin must be placed under 'Pages' plugin on the /admin/plugins page.

Absolutely perfect !

Thanks again.

CKEditor

For Apache:

Add the correct MIME type for `.mjs`:

<IfModule mod_mime.c>
    AddType application/javascript .mjs
</IfModule>

Then restart Apache (for example, `systemctl restart apache2` or `httpd`).

For nginx:

Make sure `.mjs` is mapped to JavaScript in the `http` block:

http {
    include mime.types;

    types {
        application/javascript  js mjs;
    }

    # ...
}

If you already have a `types` block with `application/javascript js;`, just add `mjs`:

types {
    application/javascript  js mjs;
}

Then reload nginx:

nginx -t
systemctl reload nginx

TinyMCE

These TinyMCE errors mean that the JavaScript files for icons and plugins are not being correctly loaded from the URLs TinyMCE expects (missing files, wrong paths, or HTML error pages instead of JS).

- Check that the files really exist

Open these URLs directly in the browser:

- http://192.168.50.162/cache/1772092595/default/tinymce/icons/default/icons.min.js
- http://192.168.50.162/cache/1772092595/default/tinymce/plugins/autosave/plugin.min.js
- http://192.168.50.162/cache/1772092595/default/tinymce/plugins/emoticons/plugin.min.js

etc

- Run 'Upgrade' via administration to clean the caches

- Clear the browser's caches

The direct links to the cache work perfectly. Otherwise, it wouldn't work with other browsers.

But I solved the problem !!!

Apparently, Firefox was experiencing an intermittent cache management issue for the editor. (in my case)

I proved it by disabling "simplecache" in the administration panel, and it worked (slowly).

So I re-enabled "simplecache" in the administration panel, and removed the "php_opcache.dll" extension from my PHP 8.4.18 server.

Now it works perfectly with Firefox !!!

Thanks, Nikolai, for your help.
