Please use the full path to your data directory, e.g.:

/www/domainame.co.uk/G/data/

Watch a process on https://www.youtube.com/watch?v=1kY_U3USWX0

I have tried using the path to my Data directory which is > /www/DATA

This is not working also. The error i get is this > Your data directory /www/DATA does not exist.

1. The characters are case sensitive.

If your folder is named "data" then you should enter "data" but not "DATA".

2. Check the permissions on this directory.

Already discussed here (read my replies)

One question still, though: Is it possible to install additional CKEditor features, like the TOC feature for example?

Yes, you can enable different features of CKeditor on the settings page.

Some features (like TOC) may not be available because they're paid plugins. Elgg comes with the full CKEditor 5 editor with all the free plugins.

Ah, great. Thanks.

Usually we use this class constructor:

class MyObject extends \ElggObject {

    const SUBTYPE = 'my_object';

    protected function initializeAttributes() {
      parent::initializeAttributes();
      $this->attributes['subtype'] = self::SUBTYPE;
    }

}

Yes, i have this class constructor. "ElggCoaching" with subtype as "coaching"

Rohit,

It looks like you did everything correct.

You mentioned that your plugin is still disabled, that is why you get the warning. The system can't find your custom class. Once you plugin is active it should go away.

However, I believe I may also need to migrate existing river items, because even though the updated class is ElggCoaching, the entities are still being treated as ElggObject instead of the new class.

No need, once you activate your plugin the system will handle this. (There is no reference in the river table to an Entity class).
