After updating Toolset Blocks to version 1.6.21, Toolset dynamic blocks (Featured Image, Post Title, Post Categories with dynamic source) stopped working or disappeared in the editor, especially inside View templates.
With the previous version (1.6.16), everything worked correctly.
The issue occurred in a setup using the Kadence theme and only appeared after updating Toolset Blocks.
Solución:
The issue was identified as a plugin/theme conflict involving Toolset Blocks 1.6.21. To work around and diagnose the problem, the following steps were taken:
Downgrade Toolset Blocks to a previous stable version (e.g. 1.6.16 or 1.6.20) downloaded from the Toolset account.
Isolate the conflict by:
Deactivating all plugins except Toolset.
Switching temporarily to a default WordPress theme (e.g. Twenty Twenty).
Test which Toolset Blocks version introduces the issue before updating on a production site.
Using these steps, the site remained functional by staying on a stable Toolset Blocks version while confirming the source of the conflict.
