Error on moodle 3.11 (php 8)

[Mikkeljeppesen1]

We have trouble with the plugin on moodle 3.11.9 (2021051709) with the version of local_pages being 2021110400

We got the problem when we upgraded the php version to php 8.0. Now were not able to edit or add a page (see the image below for debug info)

Try editing local/pages/forms/edit.php changing line 237 from:

        $records = json_decode($this->_pagedata);

to:

        $records = empty($this->_pagedata) ? array() : json_decode($this->_pagedata);

I see PR #42 also includes a fix for this.
