Why do I get a Joomla 500 error when I enable mod_rewrite?

Apache is rejecting a directive in .htaccess , most often Options +FollowSymLinks , or mod_rewrite is not allowed. Check the error log, then comment FollowSymLinks and confirm AllowOverride.

Is the administrator also down during a rewrite 500?

Not always. /administrator/ can still load while the public site 500s. That pattern strongly points at front-end rewrite rules rather than a total PHP crash.

Should I delete .htaccess permanently?

No. Use a rename only to diagnose. Joomla needs a valid .htaccess for clean SEF URLs and basic exploit blocking from the core template.

Does this apply to Joomla 5 and Joomla 6?

Yes. The SEF and htaccess.txt flow is the same family on Joomla 4, 5, and 6. Always copy htaccess.txt from your exact version package.

What if I am on Nginx?

Do not chase mod_rewrite. Configure Nginx try_files $uri $uri/ /index.php?$args; (or your host’s Joomla snippet) instead of Apache .htaccess .

Can a plugin cause a rewrite 500?

Yes. Security and SEF extensions sometimes append invalid rules. Disable recent extensions, restore the core SEF block, then re-add custom rules one by one.

Where can I get a clean Joomla htaccess file?

From the htaccess.txt in your Joomla root or install package. Our htaccess for Joomla article covers version-specific notes and hardening.
