WordPress链接跳转404错误求助：使用site_url生成子页面链接异常

Hey there, sorry to hear your previously working link is throwing a 404! Let’s walk through the most common fixes for this issue step by step:

• First, double-check your page’s slug and status
  WordPress uses the page’s slug to map to the page-{slug}.php template. Head to your WordPress dashboard, find the "Projekti" page, and confirm:

  • Its slug is exactly projekti (no extra characters, spaces, or typos)
  • The page is published (not set to Draft, Private, or Trashed)

• Refresh your permalink settings
  This is the #1 fix for random WordPress 404s. Go to Settings → Permalinks in your dashboard, don’t change any settings—just click "Save Changes". This regenerates the .htaccess file and resets WordPress’s rewrite rules, which often gets corrupted after updates or plugin changes.

• Verify the URL generated by site_url()
  Temporarily add a line to output the exact URL your code is generating:

  <?php 
  $projekti_url = site_url('/projekti/');
  echo "Generated URL: " . $projekti_url; 
  ?>
  

  Make sure the URL matches the actual permalink of your "Projekti" page. If it’s pointing to a wrong domain or has a typo (like /projekt/ instead of /projekti/), that’s the issue.

• Check your .htaccess file
  Ensure your site’s root .htaccess file exists, has the correct permissions (usually 644), and contains the default WordPress rewrite rules:

  # BEGIN WordPress
  <IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]
  </IfModule>
  # END WordPress
  

  If the file is missing or has incorrect content, replace it with the code above (just make sure to back up the original first!).

• Rule out plugin or theme conflicts
  Recent plugin installs, updates, or theme changes can break permalinks. Try:

  1. Switching to a default WordPress theme (like Twenty Twenty-Four)
  2. Disabling all plugins
     Then test the link again. If it works, re-enable plugins one by one (or switch back to your theme) to find which one is causing the conflict.

• Confirm your template file is correctly named
  Double-check that your theme folder has a file named page-projekti.php (case-sensitive on Linux servers—so avoid capital letters like Page-Projekti.php). Also, ensure the file has no syntax errors that might prevent WordPress from recognizing it.

Since the link worked before, the problem is almost certainly a broken rewrite rule, a changed page slug, or a recent conflict. Start with refreshing permalinks—it’s quick and solves most cases!
