Troubleshooting Your Apache 404 Errors (Non-Homepage Routes)

Hey there, let's tackle this 404 issue head-on. You mentioned only your homepage works while every other link throws that Apache 404 message—and since you noted past config fixes solved similar problems, we'll focus on the most likely culprits in your provided files.

First, the Most Likely Fix: `.htaccess` RewriteBase Misconfiguration

Looking at your .htaccess file, the biggest red flag is this line:

RewriteBase /var/www/html

RewriteBase should be a path relative to your Apache DocumentRoot (which is set to /var/www/html in both your virtual host configs). Using an absolute filesystem path here breaks the rewrite rules—Apache can't map clean URLs like /albums to the actual albums.php file correctly.

Fix Step 1: Correct the RewriteBase

Change that line to:

RewriteBase /

Second, Fix the Truncated `.htaccess` Content

Your .htaccess ends abruptly with:

Rewrite

This incomplete line will cause Apache to ignore or fail the rewrite rules entirely. Make sure you paste the full, complete content of your .htaccess—check for any missing rules or syntax errors at the end.

Additional Checks & Verifications

1. Ensure mod_rewrite is Enabled

Even though your .htaccess uses <IfModule mod_rewrite.c>, double-check the module is active:

sudo a2enmod rewrite

If it wasn't enabled, restart Apache afterward:

sudo systemctl restart apache2

2. Verify File Existence & Permissions

Make sure all the target PHP files (like albums.php, signup.php, inbox.php, etc.) exist in /var/www/html and are readable by the Apache user (www-data):

ls -l /var/www/html

If permissions are off, fix them with:

sudo chown -R www-data:www-data /var/www/html
sudo chmod -R 755 /var/www/html

3. Check Apache Error Logs

For more detailed clues, look at Apache's error log:

tail -f /var/log/apache2/error.log

Visit a broken page like /albums while watching the log—you'll see exactly what path Apache is trying to access, which can confirm if the rewrite rules are working as expected.
