From 404 Not Found to 500 Internal Server Error and SSL issues — learn what causes these errors and how to fix them step by step.
Website errors are inevitable — but they shouldn't stay unfixed. They damage user experience, hurt your SEO rankings, and can cost you customers. Here's how to diagnose and fix the most common ones.
A 404 means the page doesn't exist. Common causes: deleted pages, changed URLs without redirects, typos in links. Fix: set up 301 redirects from old URLs to new ones. Create a helpful custom 404 page. Use Google Search Console to find 404 errors and fix them systematically.
A generic server error with many possible causes. On WordPress: deactivate plugins one by one to find the culprit, switch to a default theme, increase PHP memory limit. Check your error logs in cPanel or hosting dashboard for specific error messages.
ERR_SSL_PROTOCOL_ERROR and mixed content warnings drive users away and hurt SEO. Ensure your SSL certificate is valid and not expired. Force HTTPS in your.htaccess file. Update all internal links and media URLs to HTTPS. Use a plugin like Really Simple SSL on WordPress.
A redirect loop where your site keeps redirecting to itself. Common cause: incorrect HTTPS redirect settings, CDN or proxy misconfiguration, WordPress URL settings mismatch. Fix: clear cache, check.htaccess redirects, verify WordPress site URL settings in database.
DNS_PROBE_FINISHED_NXDOMAIN means the domain can't be resolved. Could be a propagation issue after changing hosts (wait 24-48 hours), expired domain, or incorrect DNS settings at your registrar. Verify your DNS records point to the correct IP address.
Most website errors are fixable within minutes once you know what to look for. The key is not to panic — read the error carefully, search for it specifically, and follow the fix methodically.
