DIVI编辑器内CSS正常，WooCommerce登录后前端渲染无样式求助

Let’s walk through the most common fixes for this frustrating issue—since the Divi editor shows the page correctly, the problem is almost always related to asset loading, caching, or conflicts rather than the page design itself.

• Clear every layer of cache first
  Caching is the #1 culprit here. Start with:

  • Your browser cache: Press Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac) to do a hard refresh.
  • Plugin cache: If you use a caching plugin like WP Rocket or W3 Total Cache, go to its settings and clear all cached files.
  • Server/CDN cache: If your hosting uses server-side caching (e.g., SiteGround’s SG Optimizer) or a CDN like Cloudflare, purge those caches too.

• Disable plugin conflicts
  A third-party plugin might be blocking Divi or WooCommerce’s CSS from loading. Here’s how to test:

  1. Deactivate all plugins except WooCommerce and Divi.
  2. Check if the frontend shop page loads correctly now.
  3. If it does, reactivate plugins one by one, checking the page after each activation to find which one is causing the conflict.
     Pro tip: Use the Health Check & Troubleshooting plugin to do this without affecting your live site for other visitors.

• Verify Divi and WooCommerce integration settings
  Double-check that Divi is properly configured to work with WooCommerce:

  1. Go to Divi > Theme Options > WooCommerce and ensure the "Enable Divi for WooCommerce" toggle is turned on.
  2. Confirm your shop page is correctly set: Go to WooCommerce > Settings > Products and make sure the "Shop page" dropdown is pointing to your actual shop page (the one you edited in Divi).
  3. On the shop page itself, edit it with Divi and check that you’re using the Divi Builder (not the default WordPress editor) and that no custom code snippets are overriding the template.

• Check for CSS loading errors in the browser console
  The unstyled page usually means CSS files aren’t loading. To diagnose:

  1. On the broken frontend shop page, right-click and select "Inspect" to open the browser dev tools.
  2. Go to the Console tab and look for red error messages (like 404 Not Found for CSS files) or blocked resources.
  3. If you see 404 errors for Divi/WooCommerce CSS files, this could be a file permission issue—check that your wp-content/themes/divi and wp-content/plugins/woocommerce folders have correct permissions (usually 755 for folders, 644 for files).

• Reset permalinks
  Sometimes corrupted permalinks can break asset loading. Fix this quickly:

  1. Go to Settings > Permalinks in your WordPress dashboard.
  2. You don’t need to change anything—just click the Save Changes button. This will refresh your permalink structure.

• Reinstall Divi/WooCommerce (last resort)
  If none of the above works, try reinstalling the latest versions of Divi and WooCommerce. Always backup your site first (use a plugin like UpdraftPlus to save your files and database). Then:

  1. For Divi: Go to Appearance > Themes, switch to a default theme temporarily, delete Divi, then re-upload and activate it.
  2. For WooCommerce: Go to Plugins > Installed Plugins, deactivate and delete WooCommerce, then reinstall it from the plugin repository.

• Check if the issue only happens when logged in
  You mentioned the problem started after logging into WooCommerce. If the frontend works fine when you’re logged out, this points to a conflict with a plugin or custom code that runs exclusively for logged-in users (like a membership plugin, security plugin, or custom functions). Test this by logging out and checking the page again.
