WordPress子目录部署后线上页面异常，wp-admin报404求助

Hey Adrian, let's work through this step by step—this exact set of issues is super common when moving a local WordPress site to a live host, especially with subdirectory data setups and UK2's specific server configs. Here's how to fix each problem:

Your local WAMP setup uses localhost/[your-path] for asset URLs, but your live UK2 site is using your domain. WordPress is still trying to pull CSS/JS from your local server, which is why you only see plain text. Here are two reliable fixes:

• Option 1: Edit wp-config.php (fastest, no admin access needed)
  Open your root wp-config.php file and add these lines right above the /* That's all, stop editing! Happy publishing. */ comment:

  define('WP_HOME', 'https://yourdomain.com');
  define('WP_SITEURL', 'https://yourdomain.com');
  

  If your WordPress data (wp-content, wp-includes) lives in a subdirectory like /wp-data, adjust WP_SITEURL to https://yourdomain.com/wp-data
• Option 2: Update via Database (if wp-config tweaks don't stick)
  Use UK2's phpMyAdmin tool to access your WordPress database, find the wp_options table, and update:
  • The siteurl field to your live domain (plus subdirectory path if applicable)
  • The home field to your live domain root

UK2's Apache servers often need a specific .htaccess configuration, especially if you're using a subdirectory for data. Replace your root .htaccess file with this (adjust the RewriteBase line if your WordPress core is in a subdirectory):

# 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 your WordPress core is hosted in a subdirectory like /wp-core, change RewriteBase / to RewriteBase /wp-core/

• Enable mod_rewrite: UK2 might have this disabled by default. Log into your cPanel, navigate to "Apache Modules" and ensure mod_rewrite is checked. If you don't see this option, shoot UK2 support a quick message—they can enable it for you in minutes.
• Check File Permissions: Set your wp-content folder to permission 755 and all files inside to 644. UK2's servers are strict about permissions, and incorrect settings can block asset loading entirely.

• After making these changes, hard-refresh your browser (Ctrl+Shift+R on most browsers) to force fresh asset loading—don't skip this, cached local assets will still break things.
• If wp-admin still throws a 404, add define('FORCE_SSL_ADMIN', true); to your wp-config.php if you're using HTTPS (most UK2 plans include free SSL now).
• If you're using a custom data subdirectory (not the default wp-content), double-check that your wp-config.php has the correct definitions for WP_CONTENT_DIR and WP_CONTENT_URL pointing to your live subdirectory path.
