Bluehost error

Updated 11 October 2026

Short answer

Most Bluehost sites run WordPress on shared hosting, so the common errors are the common WordPress-on-shared-hosting errors: a plugin or theme failing after an update, a broken .htaccess file causing 500 errors, PHP memory limits, and 503 errors when the account hits its resource limits. If the browser says the site can't be reached, check the domain and DNS instead. Start with the exact error message.

What's the problem

Your Bluehost site shows an error (500, 503, a critical error, a database error, a white page) or won't load at all.

Why it happens

  • A WordPress plugin or theme failing, usually after an update.
  • A corrupted .htaccess file, a common cause of 500 errors.
  • PHP memory limits, which are tighter on shared hosting.
  • Account resource limits reached during traffic spikes, giving 503 errors.
  • The domain or DNS: expired, or nameservers not pointing at Bluehost.
  • A Bluehost service problem.

How to fix it

  1. Note the exact error and whether /wp-admin loads.
  2. For a 500 error, rename .htaccess to .htaccess_old in the site's root folder and reload. See WordPress 500 error.
  3. For a critical error or white page, disable plugins. See WordPress white screen.
  4. For 503 errors, check your account's resource usage in the hosting panel.
  5. If the site can't be reached, check the domain and its DNS. See domain not working.
  6. Contact Bluehost support with the error and when it started.

What Preventionlabs checks

One click runs the full report on your domain. For this problem it shows whether your site loads, how fast, and where its redirects go; uptime checked every 5 minutes, with an email when the site goes down and when it is back; up to 50 pages from your sitemap, listing any that fail or are slow, plus broken links on them; your DNS: nameservers, addresses, DNSSEC, and records pointing at services that no longer exist; your domain's registration and expiry date. It has no connection to your host, so check the host's status page and logs as well.
