When I launched my blogging tips site, fishingword.com, on Hostinger, I was thrilled—until I hit my first WordPress issue. A plugin crashed my homepage, leaving me staring at a blank screen. Panic set in, but I learned that WordPress troubleshooting is manageable, even for beginners. With over 45% of websites running on WordPress in 2025, glitches like slow loading, login errors, or broken pages are common. The good news? Most can be fixed without coding.

This beginner’s guide to WordPress troubleshooting walks you through the most frequent issues—white screen of death, slow site, plugin conflicts, login problems, and more—based on my experience with fishingword.com. I’ll share step-by-step fixes, Hostinger-specific tips, preventive tools, and answer a key question: Can I switch hosting providers later? Whether you’re blogging, selling products, or showcasing a portfolio, mastering WordPress troubleshooting will save you stress. Let’s fix those issues!

Why WordPress Troubleshooting Matters

WordPress is powerful but not perfect. A single misstep—like a bad plugin or outdated theme—can break your site, frustrate visitors, or hurt your Google rankings. WordPress troubleshooting helps you:

  • Restore access: Regain control if you’re locked out.
  • Boost performance: Speed up your site to keep readers engaged.
  • Enhance security: Fix vulnerabilities to protect your data.
  • Save time: Avoid hours of Googling or costly developer fees.

When I faced the white screen of death , Hostinger’s support and a few WordPress troubleshooting tricks got me back online in under an hour. This guide covers the top issues beginners face in 2025, with Hostinger-focused solutions to make WordPress troubleshooting a breeze.

Common WordPress Issues and Fixes

Here are the five most common WordPress problems I’ve encountered, with detailed WordPress troubleshooting steps. Each fix is beginner-friendly, using Hostinger’s tools and free plugins.

1. White Screen of Death (WSOD)

What it is: Your site shows a blank white page, often due to a plugin conflict, theme error, or memory limit issue.

How to fix:

  1. Deactivate plugins:
    • Log in to yourwebsite.com/wp-admin. If inaccessible, use Hostinger’s File Manager (hPanel > File Manager).
    • Navigate to /wp-content/plugins/, rename the plugin folder (e.g., wpforms to wpforms-off) to disable it.
    • Check if the site loads. Reactivate plugins one by one to identify the culprit.
  2. Switch to a default theme:
    • In File Manager, go to /wp-content/themes/, rename your active theme (e.g., blocksy to blocksy-off).
    • WordPress reverts to a default theme (e.g., Twenty Twenty-Five).
  3. Increase memory limit:
    • In File Manager, edit wp-config.php (in the root folder).
    • Add: define('WP_MEMORY_LIMIT', '256M'); above /* That's all, stop editing! */.
    • Save and refresh your site.

Hostinger tip: Use Hostinger’s PHP Configuration tool (hPanel > Advanced > PHP Configuration) to increase memory to 256MB without editing files.

Pro tip: Test plugins on a Hostinger staging site before going live. See our How to Install WordPress Plugins.

2. Slow Loading Site

What it is: Pages take over 3 seconds to load, driving visitors away.

How to fix:

  1. Enable caching:
    • Install LiteSpeed Cache (free) via Plugins > Add New. Search “LiteSpeed Cache,” click Install Now, then Activate.
    • In the LiteSpeed Cache settings, enable page caching and image optimization.
  2. Optimize images:
    • Use Smush (free) to compress images without quality loss. Install via the plugin dashboard.
    • Run Smush’s bulk optimization on your media library.
  3. Minimize plugins:
    • Go to Plugins > Installed Plugins, deactivate unused plugins (e.g., test plugins).
    • Keep 5–7 active plugins, like Rank Math and WPForms, for speed.
  4. Check hosting performance:
    • Hostinger’s LiteSpeed servers are optimized for speed. If issues persist, contact 24/7 support via hPanel.

Hostinger tip: Use Hostinger’s Performance tab (hPanel > Performance) to enable automatic caching and monitor load times.

Pro tip: Test your site with GTmetrix (free) to pinpoint slow elements. Try GTmetrix .

3. Plugin or Theme Conflicts

What it is: A plugin or theme causes errors, like broken layouts or missing features.

How to fix:

  1. Deactivate plugins:
    • In Plugins > Installed Plugins, select all plugins, choose Deactivate, and apply.
    • Reactivate one by one, checking the site after each to find the conflict.
  2. Switch themes:
    • Go to Appearance > Themes, activate a default theme (e.g., Twenty Twenty-Five).
    • If the issue resolves, your theme is the problem—update or replace it.
  3. Check compatibility:
    • Ensure plugins/themes are compatible with WordPress 6.6 (check WordPress.org).
    • Update all plugins/themes via Dashboard > Updates.

Hostinger tip: Use Hostinger’s staging site (hPanel > WordPress > Staging) to test updates without affecting your live site.

Pro tip: Stick to reputable plugins like WPForms. See our Best WordPress Plugins for Beginners.

4. Can’t Log In to WordPress Admin

What it is: You’re locked out of yourwebsite.com/wp-admin due to wrong credentials, security blocks, or errors like “403 Forbidden.”

How to fix:

  1. Reset password:
    • Go to yourwebsite.com/wp-login.php, click Lost your password?
    • Enter your email or username, reset via the link sent.
  2. Check .htaccess:
    • In Hostinger’s File Manager, find .htaccess in the root folder.
    • Rename it (e.g., .htaccess-old) to disable it, then try logging in.
    • Regenerate via Settings > Permalinks > Save Changes.
  3. Disable security plugins:
    • In File Manager, go to /wp-content/plugins/, rename security plugins (e.g., wordfence to wordfence-off).
  4. Contact Hostinger:
    • If locked out, Hostinger’s support can reset admin access via hPanel.

Hostinger tip: Use Hostinger’s Security tab (hPanel > Security) to check for IP blocks or malware causing login issues.

Pro tip: Enable two-factor authentication with Wordfence to prevent future lockouts.

5. 404 or 500 Errors

What it is: Visitors see “404 Not Found” (page missing) or “500 Internal Server Error” (server issue).

How to fix:

  1. Fix 404 errors:
    • Go to Settings > Permalinks, select “Post name,” and click Save Changes.
    • Check for broken links using Rank Math (free) in SEO > Redirections.
  2. Fix 500 errors:
    • Enable debug mode: In File Manager, edit wp-config.php, add define('WP_DEBUG', true); above /* That's all, stop editing! */.
    • Refresh your site to see error messages, then search them on WPBeginner.
    • Deactivate plugins/themes as in the WSOD fix.
  3. Check server status:
    • Visit Hostinger’s status page (status.hostinger.com) for outages.
    • Contact support if server-side issues persist.

Hostinger tip: Hostinger’s Server Status tool (hPanel > Advanced > Server Status) shows real-time performance metrics.

Can I Switch Hosting Providers Later?

A common concern during WordPress troubleshooting is whether you’re stuck with your current host if issues persist. The good news: Yes, you can switch hosting providers later, and it’s easier than you think, especially with Hostinger’s free migration service. If you need to switch, here’s how:

Steps to switch:

  1. Choose a new host:
    • Pick from the top hosting providers like Hostinger, Bluehost, or SiteGround (see our Top Hosting Providers Compared for 2025).
    • Hostinger’s $2.99/month plan is ideal for beginners, with free migrations and a 1-click WordPress installer.
  2. Backup your site:
    • Use UpdraftPlus (free) to back up your WordPress files and database. Install via Plugins > Add New.
    • Download the backup to your computer or store it in Google Drive.
  3. Request a migration:
    • Hostinger offers free migrations (hPanel > WordPress > Migrate Website). Submit your current host’s details, and their team handles the rest.
    • Other hosts like A2 Hosting also provide free transfers.
  4. Update DNS settings:
    • After migration, update your domain’s nameservers to point to the new host (e.g., Hostinger’s nameservers: ns1.dns-parking.com, ns2.dns-parking.com).
    • Find these in hPanel > Domains > DNS/Nameservers.
  5. Test your site:
    • Check yourwebsite.com on the new host to ensure all pages, plugins, and forms work.
    • Use Hostinger’s staging site to test before going live.

Hostinger tip: Hostinger’s migration team moved a friend’s site in 24 hours, with zero downtime. Contact support via hPanel for assistance.

Things to consider:

  • Downtime: Minimal with free migrations (Hostinger ensures <1 hour).
  • Cost: Check renewal prices (e.g., Hostinger’s $11.99/month vs. SiteGround’s $17.99/month).
  • Compatibility: Ensure your plugins/themes work with the new host’s servers (e.g., Hostinger’s LiteSpeed).
  • Timing: Migrate during low-traffic periods to avoid disruptions.
