FTP connection times out repeatedly

- Switch from active to passive mode in FileZilla or your FTP client settings - Add your current IP address to the allowed FTP access list in security settings - Use port 22 for SFTP instead of standard FTP port 21 - Check if your firewall blocks outgoing connections on FTP ports - Try the web-based File Manager as an alternative if FTP keeps failing

Service info and troubleshooting

Website returns 500 Internal Server Error: Your site throws a 500 error when visitors try to access it. First, check your .htaccess file — a single syntax mistake breaks everything. Log into your hosting control panel and temporarily rename .htaccess to .htaccess_old. If the site loads, you found the culprit. Also, check PHP memory limits in your account settings. WordPress sites especially need at least 256MB. If you recently installed a plugin or theme, deactivate it through FTP by renaming its folder.

Cannot access Control Panel dashboard: Clear your browser cache completely, then try incognito mode. The dashboard uses session cookies that sometimes corrupt. If you're still locked out, reset your password through the recovery email. Make sure you're using the correct login URL for your specific data center — European accounts use different endpoints than US accounts. Disable browser extensions temporarily, especially ad blockers and privacy tools that interfere with authentication tokens.

Database connection error on website: Your database credentials likely changed or the connection limit maxed out. Log into phpMyAdmin and verify the database name, username, and password. Update your config file (wp-config.php for WordPress, configuration.php for Joomla) with correct details. If you hit connection limits, optimize your database tables and enable caching to reduce queries. Check if your database host is localhost or a specific server address.
