Block validation errors on save
You edit a post and Gutenberg throws "This block contains unexpected or invalid content." Usually a block markup drift, a custom block registration issue, or a React mismatch. We diagnose and fix.
Gutenberg support
Gutenberg and Block Editor support for modern WordPress.
Custom block development, block validation errors, theme.json configuration, full-site-editing problems, and reusable block management. We build and maintain Gutenberg-first sites.
Common issues
Gutenberg (Block Editor) problems we see every week.
If any of these sound familiar, we have fixed it before. Most engagements start with one of these and end with the site on a care plan.
Custom blocks not rendering correctly
A custom block saves fine but renders wrong on the front end, in the editor, or both. Usually a save function mismatch or a dynamic render callback error. We audit and patch.
theme.json settings not applying
Block theme customizations in theme.json get ignored, overridden, or partially applied. We audit the settings hierarchy and override precedence.
Full Site Editing templates not loading
Block theme templates disappear, revert to defaults, or show the wrong layout. We diagnose template resolution and template-part registration.
Reusable blocks missing after update
Reusable blocks show as empty, return to default content, or throw errors. Usually a post-type migration issue after WordPress core updates. We restore.
Gutenberg and classic editor conflicts
Some posts edit in Gutenberg, some in Classic Editor, and the switching breaks formatting. We standardize the editor strategy and clean up mixed content.
