Common DirectAdmin Errors and Fixes

Most errors on a DirectAdmin website come from a short list of causes: a bad .htaccess line, a PHP fatal error, wrong permissions, a resource limit or a database setting. This guide lists the errors you are most likely to see on Domain India's DirectAdmin shared hosting, what each one means on our servers, and the fix, with links to the full guide for each.

1. First step for any error: read the log

Older monthly logs are archived in domains/yourdomain.com/logs/ in your home folder. The full walkthrough is in How to access and analyse logs in DirectAdmin.

2. Error quick reference

3. 500 Internal Server Error

Check these in order:

• PHP settings in .htaccess. Our servers run PHP through PHP-FPM, not as an Apache module, so any php_value or php_flag line in .htaccess gives a 500 for the whole site. Remove it and set the value in a .user.ini file instead.
• A disallowed Options value. DirectAdmin allows only Indexes, IncludesNOEXEC, MultiViews, SymLinksIfOwnerMatch, FollowSymLinks and None in .htaccess. Anything else, such as +ExecCGI, gives a 500.
• Test .htaccess itself. Rename it to .htaccess.bak in File Manager. If the site loads, the problem is in that file; restore it and remove lines until you find the one that breaks.
• A PHP fatal error. The error_log file names the file and line; a path inside wp-content/plugins/ names the plugin.
• Memory or process limits. A 500 that comes and goes at busy times is often a resource limit, not a code fault. See section 6.

The full checklist is in Troubleshooting 500 Internal Server Error.

4. 403 Forbidden

• No index file. The folder needs an index.html or index.php. Note that DirectAdmin serves index.html before index.php, so a leftover placeholder index.html hides your PHP site.
• Permissions. Folders should be 755 and files 644. On our DirectAdmin servers your home folder is 710, domains is 711 and public_html is 755; don't change those. Never set 777: it is unsafe and not needed.
• A deny rule. Look for Require all denied or Deny from lines in .htaccess, including in parent folders.
• Your own IP is blocked. If every site on the server refuses you but works on mobile data, the server firewall may have blocked your IP after failed logins. Contact support with your public IP address.

5. 404 Not Found

• Files in the wrong folder. Each domain's website lives in domains/yourdomain.com/public_html.
• WordPress posts return 404 but the home page works. In WordPress, open Settings › Permalinks and click Save Changes to rewrite .htaccess. mod_rewrite is loaded on our DirectAdmin servers.
• Custom 404 page. DirectAdmin on our servers has no Custom Error Pages tool. Put an ErrorDocument 404 /404.html line in .htaccess, or place a 404.shtml page in public_html, which the server serves for missing pages; see Managing custom error pages in DirectAdmin.

6. 508 Resource Limit Is Reached, and 503

Our DirectAdmin servers run CloudLinux, which gives each account its own limits. A 508 means your account hit its entry-process limit: too many PHP requests running at once. Memory and process limits show up as 500 or 503 errors instead.

Fix the cause before upgrading: cache pages (on WordPress, WP Super Cache or W3 Total Cache, because our shared hosting runs Apache), block abusive bots, move heavy jobs to quiet hours and put a timeout on every outside call your code makes.

7. Database connection errors

"Error establishing a database connection" or "Access denied for user" nearly always means a setting in your configuration file (such as wp-config.php) does not match what exists in DirectAdmin.

• Names are prefixed. DirectAdmin adds your username to database and user names, for example username_wp. Use the full names.
• The user must be granted access to the database, and the password in the config file must match.
• The host is localhost for a site on the same account.
• Remote connections: port 3306 is closed from outside on our shared servers, so connect from your own computer through an SSH tunnel. Jailed SSH is available on every shared plan; it is off by default, so ask support to enable it, and log in with a key.

8. PHP limits: disabled functions and uploads

"Function has been disabled for security reasons." Our DirectAdmin servers disable functions that run system commands, including exec, shell_exec, system, proc_open and popen, and on most sites curl_exec and curl_multi_exec too. A plugin that needs one of them shows this warning or a fatal error. allow_url_fopen is on. If a Composer install stops with a proc_open message, run it again with --no-scripts, or build locally and upload the vendor folder. The full list and workarounds are in PHP disabled functions on shared hosting.

Uploads. PHP accepts uploads up to 64 MB by default on our DirectAdmin server. To raise upload_max_filesize and post_max_size, add them under Account Manager › PHP Settings › Add New Override, or use a .user.ini file in public_html; never php_value in .htaccess. DirectAdmin's File Manager accepts files up to 500 MB, and FTP is the better route for very large files. Also check your disk space. See PHP upload filesize limit.

9. SSL errors

Free Let's Encrypt certificates are issued from DirectAdmin and renew automatically, about a month before they expire. A new certificate can only be issued once the domain and www point to your hosting. If the browser warns after the certificate is in place, look for mixed content: images or scripts still loaded over http://. Steps: How to enable Let's Encrypt SSL in DirectAdmin.

10. Where Domain India fits

Domain India DirectAdmin hosting runs the setup described in this guide: CloudLinux account limits, PHP-FPM with PHP versions up to 8.3, free Let's Encrypt SSL, and weekly JetBackup backups you can restore from in the panel (see Restoring from JetBackup in DirectAdmin). If an error turns out to be a resource limit that caching and bot blocking don't fix, an active plan can be upgraded at any time from Hosting › My hosting with Change plan.

DirectAdmin plans start at ₹100 a month (Domain India list prices on 19 September 2026, excluding 18% GST); compare them on the DirectAdmin hosting page.
