Review an issue, make a supported repair, and check the result.

Fix one issue

1. Open the item in Fixes and inspect the affected page, element, or setting. Technical details are one click away. See it highlights the problem on a preview of the page, and the Pages screen lists every page with how many fixes each one needs.
2. If a Fix is available, read what it changes. Not every item has an automatic repair; those come with simple steps instead.
3. Apply it, then check the page as a visitor.
4. If the result is wrong, use Undo next to the change in Undo history.
5. Use Check my site again on Home to confirm the issue is gone rather than assuming a saved change solved it. Fixed items leave the list as soon as you fix them.

What can be repaired?

The available fix depends on the issue and builder. Examples include headings, supported image alt text and accessible names, page SEO fields, and low-contrast text, which you can swap for the nearest accessible colour in one click, with Undo. With Checknaut Pro, which includes the Privacy Pack, Checknaut can also create missing legal pages as drafts for you to review. Some image optimizations use WordPress's image editor; file support and safe reference updates depend on the installation. A refused or unchecked image is not an optimized one.

Images: Fit to slot, compression and alt text

• Fit to slot crops and compresses an image to what the page shows. Checknaut measures the page in your browser at seven common widths plus your theme's breakpoints, writes a smaller WebP beside the original (AVIF is an option in Settings), and compares before and after. If its checks detect a visual regression, that page is put back and the reason is shown. The comparison uses sampled widths and a visual-similarity threshold; review important pages after fitting. Lightbox, gallery, parallax, animated, featured, social and logo images are only resized, never cropped. Free fits one image at a time; Pro fits every image your pages use from Tools › Speed tools.
• Compression writes a smaller WebP beside the original and scales very large images down. Pro compresses all used images in one resumable run that can be undone as a whole.
• Alt text sync for Divi brings Divi image modules that show an empty or old alt in line with the Media Library: page by page free, the whole site with Pro.
• AI alt text (Pro) drafts descriptions for used images that have none. In bulk, nothing is applied until you approve each one.
• Replace an image (Pro) puts a new file into the same image so every page using it updates, and location data can be removed from photos. Both can be undone.

Original files are never changed or moved. Image undos go newest first: undo a later fit before an earlier compression of the same image.

Fix one cause across many pages with Pro

Pro offers Fix all in wp-admin and checknaut_fix_everywhere through MCP. Read the page-by-page plan first, apply the approved scope, then check your site again. Do not turn on writes merely to silence a warning.

How Undo protects later work

Fix undo records previous values and can refuse if something changed afterwards. That protects a later human edit. Page writes preserve prior content using a WordPress revision or a saved undo slot where revisions are disabled. Design-system changes use snapshots; Pro adds rollback sessions.

What if Undo refuses?

Stop and read the reason. Check whether another editor changed the value. Compare revisions or the current page before restoring. A forced restore can remove later work; make that decision deliberately.

Do snapshots replace backups?

No. Content revisions, design snapshots, and rollback sessions cover specific plugin changes. Keep independent database and file backups, especially before updates, migrations, and media work.

Legal and accessibility limits

A fix improves the issue it addresses. It does not make a site legally compliant. Legal pages are drafts for review, and automated accessibility checks need manual testing alongside them.

Useful assistant prompt

Show the plan for fixing missing alt text on the homepage. Write descriptive alt text from what each image conveys. Preserve later edits, apply only that plan, and verify the rendered result.
