The darling of the web development world, making it ridiculously easy to get your site up and running. But as with anything that seems too good to be true, there are always a few hiccups along the way. Themes clash, plugins throw tantrums, and sometimes you just want to pull your hair out. But don’t worry! We’ve all been there.

1. The White Screen of Death (WSOD)

What is it? Imagine logging into your WordPress site and seeing… nothing. Just a white screen staring back at you like it’s challenging your very existence. This is the infamous White Screen of Death.

Why does it happen? Typically, WSOD occurs due to memory limit exhaustion, plugin conflicts, or theme issues.

Solution:

1 – Increase Memory Limit:

Open your wp-config.php file and add the following line:

define('WP_MEMORY_LIMIT', '256M');

2 – Deactivate All Plugins:

• Rename the plugins folder in wp-content to something like plugins_old. This will deactivate all your plugins.
• Refresh your site. If it works, reactivate your plugins one by one to find the culprit.

3 – Switch to Default Theme:

• Rename your current theme’s folder in wp-content/themes to something else.
• This forces WordPress to revert to a default theme like Twenty Twenty-One.

2. Plugin Conflicts

What is it? Your plugins are fighting like cats and dogs. One works, but then another crashes. Or worse, they all crash.

Why does it happen? Plugins can conflict with each other or with your theme due to incompatible code or similar functionality.

Solution:

1. Identify the Conflict:
   • Deactivate all plugins and then reactivate them one by one, checking your site each time.
   • Use the Health Check & Troubleshooting plugin to diagnose issues.
2. Update Everything:
   • Make sure all your plugins, themes, and WordPress itself are up to date. Developers fix bugs and conflicts in updates.
3. Reach Out for Support:
   • Visit the plugin’s support forum on WordPress.org. The developers and community are often very helpful.

3. 404 Errors and Broken Permalinks

What is it? You’ve just published your latest blog post, but clicking the link gives you a 404 error. Panic sets in.

Why does it happen? This usually occurs due to broken permalinks or .htaccess file issues.

Solution:

1. Reset Permalinks:
   • Go to Settings > Permalinks in your WordPress dashboard.
   • Simply click Save Changes to flush the rewrite rules.
2. Check .htaccess File:
   • Make sure your .htaccess file has the correct rules. It should look something like this:

# 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

1. Deactivate Plugins:
   • Sometimes plugins can mess with your permalinks. Deactivate them to see if the issue resolves.

For more details, check out the WordPress permalinks guide.

4. Internal Server Error (500 Error)

What is it? You’re met with a nasty “Internal Server Error” message. It’s vague, unhelpful, and just plain annoying.

Why does it happen? This could be due to corrupted .htaccess files, memory limit issues, or plugin/theme conflicts.

Solution:

1. Check .htaccess File:
   • Rename your .htaccess file to .htaccess_old.
   • Try loading your site. If it works, go to Settings > Permalinks and save changes to regenerate the .htaccess file.
2. Increase PHP Memory Limit:
   • Add this line to your wp-config.php file:

define('WP_MEMORY_LIMIT', '256M');

1. Deactivate Plugins and Themes:
   • Follow the same steps as for WSOD. Deactivate plugins and switch themes to isolate the problem.

5. Theme Customization Not Showing

What is it? You’ve customized your theme to perfection, but the changes aren’t showing up on your site. Frustrating, right?

Why does it happen? This can be due to caching issues, browser cache, or CSS conflicts.

Solution:

1. Clear Cache:
   • Clear your browser cache.
   • If you’re using a caching plugin (like WP Super Cache or W3 Total Cache), clear the plugin cache.
2. Disable Caching Plugins:
   • Temporarily deactivate caching plugins to see if your changes appear.
3. Force Refresh:
   • Press Ctrl + F5 (Windows) or Cmd + Shift + R (Mac) to force a full refresh of the page.
4. Check Child Theme:
   • If you’re using a child theme, make sure your changes are in the correct files and paths.
