Common Website Errors Explained (and How to Fix Them)
Website errors are alarming when you do not know what they mean. The good news is that each error code tells you something specific about where the problem lies - and most have straightforward causes. Here is a plain-language guide to the ones you are most likely to see.
404 Not Found
What it means: The server is working fine, but the specific page requested does not exist.
Common causes: A mistyped URL, a page that was deleted or renamed, or a broken link pointing to a page that moved.
How to fix: If it is a page you deleted intentionally, set up a redirect to the closest equivalent page so visitors and search engines land somewhere useful. If the page should exist, check that the file is actually present and correctly named - file names are case-sensitive on most servers.
500 Internal Server Error
What it means: Something went wrong on the server side, but the server cannot be more specific. This is the most common serious error and also the vaguest.
Common causes: A faulty plugin or theme, a syntax error in a PHP file, a corrupted .htaccess file, or exceeding a PHP memory limit.
How to fix:
- Check your error logs in cPanel (under Metrics, look for Errors) - this often names the exact file causing the problem
- If you recently installed or updated a plugin, deactivate it and see if the error clears
- Rename your .htaccess file temporarily to .htaccess-old; if the site loads, the file was the problem
- If you recently edited any PHP file, restore the previous version - a single missing bracket causes this
502 Bad Gateway
What it means: One server received an invalid response from another server it was relying on.
Common causes: Usually a server-side issue rather than a problem with your website's code - a service that has stopped, a temporary overload, or an issue with a CDN or proxy sitting in front of your site.
How to fix: Wait a few minutes and refresh, as these are often temporary. If it persists, contact your hosting support - this one is genuinely more likely to need their intervention than something you can fix yourself.
503 Service Unavailable
What it means: The server is up but temporarily unable to handle the request.
Common causes: Scheduled maintenance, a traffic spike exceeding your plan's resources, or a WordPress update that did not complete and left the site in maintenance mode.
How to fix: If it followed a WordPress update, look for a file named .maintenance in your public_html folder and delete it. Otherwise, check whether your host has announced maintenance, and consider whether your traffic has genuinely outgrown your current plan.
DNS Errors (Server Not Found / DNS_PROBE_FINISHED_NXDOMAIN)
What it means: The browser could not translate your domain name into a server address - so it never even reached your website.
Common causes: Nameservers not set correctly, DNS changes still propagating, or an expired domain registration.
How to fix: Confirm your domain is not expired, check that nameservers point to your host, and if you changed them recently, allow up to 24-48 hours for propagation.
Mixed Content Warnings
What it means: Your page loads over secure HTTPS, but some elements on it (images, scripts) load over insecure HTTP.
How to fix: Update those resource links to use https:// instead of http://. In WordPress, a search-and-replace on your database for the old http:// version of your domain usually resolves it.
India-Based Support When You Need It
Hostira hosting includes cPanel access with error logs, plus India-based support to help when an error genuinely needs server-side investigation.
Contact Support →A General Troubleshooting Order
- Check the error logs first - cPanel's error log usually names the culprit and saves a lot of guessing
- Ask what changed recently - a plugin, an update, an edited file, a DNS change
- Undo the most recent change and see if the error clears
- Restore from a backup if you have one and the cause is not obvious
- Contact support for anything that looks server-level (502, persistent 503)
Conclusion
Error codes are more helpful than they look - each one narrows down where the problem is. Learn to check your cPanel error log first, keep backups so you always have a way back, and you will handle most of these without needing anyone's help.
