 * Hello, To properly investigate and resolve the issue, It need some additional
   information, such as whether this error is occurring on a specific page only,
   or across the entire website? Thanks

 * **To fix the fatal error on your WordPress site (when the page won’t load):**
 * You will need access to your hosting control panel (like cPanel, Plesk, or whatever
   dashboard your hosting company gives you).
    1. **Temporarily disable all plugins (this is the safest first step):**
    2.  - Log in to your hosting control panel.
        - Open the **File Manager** tool.
        - Go to your WordPress folder (usually something like /public_html/ or /www/
          look for folders like wp-admin, wp-content, and wp-includes).
        - Inside the main WordPress folder, find the wp-content folder.
        - Look for the folder named plugins and rename it to something like plugins-
          old or plugins-disabled.
        - Save the change, then refresh your website in the browser.
        - If the error disappears and the site loads (even if it looks plain), great!
          This means one of your plugins was causing the problem.
    3. **Find the bad plugin:**
    4.  - Log in to your WordPress admin dashboard (yoursite.com/wp-admin) it should
          work now.
        - Go to **Plugins** , **Installed Plugins**.
        - Rename the plugins-old folder back to plugins (via File Manager again) this
          reactivates them all at once, but don’t worry.
        - Now, deactivate **all** plugins from the dashboard.
        - Reactivate them **one by one** (activate , refresh site , check if error 
          returns).
        - When the error comes back after activating a specific plugin, that’s the 
          culprit. Keep it deactivated for now, or look for an update/fix for it.
    5. **If renaming plugins didn’t fix it, try switching to a default theme:**
    6.  - Back in File Manager, go to wp-content/themes/.
        - Find the folder for your current theme (it might be named after your theme,
          like astra, generatepress, etc.).
        - **Rename** it to something like your-theme-old.
        - Refresh your website, WordPress will automatically switch to a default theme(
          like Twenty Twenty-Five or similar).
        - If the error goes away, the problem was with your theme. You can rename the
          old theme folder back later and contact the theme developer, or switch to
          a default one permanently.
    7. **If nothing above works (still error):**
    8.  - Go back to File Manager.
        - Navigate to: wp-includes/block-supports/layout.php
        - Open that file for editing (most hosts have an “Edit” button).
        - Find the line around 600 that has array_intersect_key( (it might look like
          $merged_layout = array_intersect_key( $something, $defaults );).
        - Add a quick safety line right before it, like:text`$something = (array) $
          something; // Force it to be an array`(Replace $something with the actual
          variable name there, often $parent_layout or $layout.)
        - Save the file and refresh your site. This is a temporary patch to get things
          working again (WordPress might overwrite it on update, so fix the real cause
          later).
        - Or contact your hosting support, show them the exact error message; many 
          hosts can help edit files or disable things quickly.
 * After the site is back up:
    - Update WordPress, all plugins, and your theme right away.
    - Clear your browser cache (Ctrl + F5 or Cmd + R).
    - If you use caching (like WP Rocket, Cloudflare), clear that too.
 * This should get your site loading again safely. If you run into trouble at any
   step (like can’t find a folder), tell me what you see in your control panel or
   the exact error now, and I can guide you more.
