Block API Version Deprecation (qsm/main-block)

Block API Version Deprecation (qsm/main-block)

Notice: Block with API version 2 or lower is deprecated since version 6.9... Set apiVersion field to 3...

The Cause: The plugin Quiz and Survey Master (qsm) registers its block qsm/main-block using apiVersion: 1. Older API versions prevent the block editor from using the isolated iframe mode.

How to Fix: If you are the developer of the qsm plugin (or maintaining custom block code):

1. Open your block’s block.json file.
2. Update or set "apiVersion": 3.

JSON

{
  "$schema": "https://schemas.wp.org/trunk/block.json",
  "apiVersion": 3,
  "name": "qsm/main-block",
  "title": "Quiz and Survey Master"
}

If you are an end user / site owner: Contact the plugin author (Quiz and Survey Master) or wait for an update. This warning will not break your site immediately.
