What’s Changed

Fixed

• Block recovery (all InnerBlocks blocks): Resolved the “This block contains unexpected or invalid content” / Attempt Recovery error that emptied ACF InnerBlocks blocks (Callout, CTA, Hero, Section, Feature Grid, Testimonial, Team Member, Opinion Box, …). The cause was inner content saved as undelimited raw HTML (e.g. a bare <p> instead of <!-- wp:paragraph -->), which the editor treats as invalid InnerBlocks markup. Clicking Attempt Recovery then rebuilt the block from its template default, wiping the author’s content.

Added

• includes/block-recovery.php — a self-healing helper that re-wraps orphaned inner HTML into proper core blocks (paragraph, heading, list, quote; anything unrecognised is preserved verbatim in a core/html block, so no content is ever lost). It is idempotent and runs in two ways:
• Live self-heal: filters the block editor’s REST content.raw (edit context only) so existing posts open cleanly with no action required; saving then persists the repaired markup.
• Permanent bulk repair: wp acf-blocks repair-content [--dry-run] [--post=<id>] rewrites affected posts in the database.
• The InnerBlocks block set is derived automatically — unioning each block.json (supports.jsx) with the live block registry (ACF can enable InnerBlocks at runtime without declaring it in block.json) — with a acf_blocks_recovery_innerblock_names filter to customise it.

Added — Block Migrator

• includes/block-migrator.php + visual Migrator on the options page (Settings → ACF Blocks License). A new Block Migrator & Repair card with Scan, Dry Run, and Migrate All actions. Every change is saved through wp_update_post() (a revision is stored), so migrations are reversible. WP-CLI parity: wp acf-blocks migrate [--dry-run].
• Reversible migrations — before each post is migrated, its original content is snapshotted both as a native WordPress revision (visible in the editor’s Revisions browser) and as a per-post restore point. A Revert Last Migration button (and wp acf-blocks migrate --revert) rolls the entire batch back to its pre-migration content, byte-for-byte, independent of the site’s revision settings.
• Legacy / renamed block migrations — blocks saved under names the plugin no longer registers are remapped to the current block with field-data translation, not just renamed:
• acf/table-of-contents, acf/table-of-content → acf/toc
• acf/productbox → acf/product-box (incl. the legacy features repeater)
• acf/accordion-item → acf/accordion (consecutive items merged into one block)
• acf/accordion-group → acf/accordion (wrapper + children merged, FAQ schema preserved)
• acf/acf-accordion → acf/accordion (acc_question/acc_answer sub-fields remapped)
• acf/poll has no current equivalent — reported and left untouched for manual handling.
• Unparseable-markup repair — fixes content the block parser chokes on:
• Orphaned closing delimiters (e.g. a stray <!-- /wp:post-content --> with no opener) that silently push every following block into freeform text. Removed with a delimiter stack so only genuinely unmatched closers are stripped.
• Dangling openers (a truncated <!-- wp:… fragment with no -->).
• Literal --> inside ACF block JSON, HTML-encoded to --> (identical when rendered).

Compatibility

• WordPress 7.0: Added Tested up to: 7.0 header. Audited for WordPress 7 / ACF Pro 6.x — all 29 blocks already use Block API v3, register via block.json (no deprecated acf_register_block_type), retain the ACF 6.7+ acf_setup_meta compatibility layer, and contain no PHP 8.2–8.5 deprecation patterns (verified against PHP 8.5).

Commits

• Release 2.8.0: block recovery + migrator with reversible migrations (fc6bc7d)
