将WordPress站点设为静态首页后服务器端页面变白问题求助

Hey Maria, let's walk through the most likely causes of that white screen issue you're facing after migrating your WordPress site to the server, and break down actionable steps to fix it:

1. Enable WordPress Debug Mode to Reveal Hidden Errors #

White screens usually mean PHP errors are being suppressed. Let's turn on debug logging to see exactly what's going wrong:

• Access your server via Cyberduck and open wp-config.php in your site's root directory.
• Add these lines right above the /* That's all, stop editing! Happy publishing. */ comment:

  define('WP_DEBUG', true);
  define('WP_DEBUG_LOG', true);
  define('WP_DEBUG_DISPLAY', true);
  @ini_set('display_errors', 1);
  

• Save the file and reload your homepage. You should now see a specific error message instead of a white screen—this will point us directly to the problem.

2. Verify Custom Page Template Setup #

Since you created a custom template for your homepage, double-check these details:

• Template Header Comment: Ensure your template file (e.g., homepage.php) starts with the required comment at the very top, no extra spaces or characters before it:

  <?php /* Template Name: Homepage */ ?>
  

• File Location: Confirm the template is uploaded to your active theme's root folder (e.g., wp-content/themes/your-active-theme/). If it's nested in a subfolder, WordPress won't detect it as a page template.
• File Integrity: Compare the file size of your local template vs. the one on the server. If they don't match, re-upload the file via Cyberduck to fix any incomplete transfers.

3. Check File Permissions #

Incorrect file permissions can prevent WordPress from reading your template file:

• In Cyberduck, right-click your template file and select Get Info (or similar) to view permissions.
• Set file permissions to 644 (read/write for owner, read-only for group and public) and folder permissions to 755. Most hosting providers require these settings for WordPress files to work correctly.

4. Validate ACF Plugin and Field Setup #

Since you're using Advanced Custom Fields, these are critical checks:

• Plugin Activation: Make sure the ACF plugin is installed and activated on your server (it might have been left out during migration).
• Field Synchronization: ACF field groups are stored in the database. If you didn't export/import your field groups from local to server, WordPress won't recognize the custom fields you're calling in your template. You can export field groups from your local WP admin (ACF > Tools > Export) and import them on the server.
• Field Key Spelling: Double-check that all get_field() or the_field() calls in your template use the exact field key/name you set up in ACF—even a small typo can cause fatal errors.

5. Fix Migration-Related Configuration Issues #

Migrations often leave behind mismatched settings:

• Site URL: Ensure your server's site URL matches what's set in WordPress. You can hardcode it in wp-config.php to avoid database mismatches:

  define('WP_HOME', 'https://your-server-domain.com');
  define('WP_SITEURL', 'https://your-server-domain.com');
  

• Database Sync: Confirm you imported the full local database to your server, including ACF field data and theme settings. Partial imports can break template functionality.

6. Audit Template Code for Local-Specific References #

If you copied code from index.php to your template, look for hardcoded local paths (e.g., C:/xampp/htdocs/your-site/)—these won't work on the server. Replace any static paths with WordPress native functions like get_template_directory_uri() or get_stylesheet_directory_uri().

Once you've worked through these steps, the white screen should either disappear or show a specific error that you can address directly. If you share the error message from debug mode, we can narrow it down even further!
