WordPress Installation Troubleshooting
When setting up a new WordPress site, users might encounter various issues that can halt the installation process. Here's a comprehensive look at common problems, their causes, and solutions:
1. Database Connection Issues
One of the most frequent errors during WordPress installation is related to database connection. This error typically appears as:
Error establishing a database connection
- Causes: Incorrect database credentials, server issues, or database corruption.
- Solutions:
- Double-check the database name, username, password, database host, and table prefix in your
wp-config.php file.
- Ensure your database server is up and running. Contact your hosting provider if you suspect server issues.
- If the database itself is corrupted, you might need to repair or restore from a backup.
File permissions issues can prevent WordPress from installing or updating:
- Causes: Incorrect permissions on WordPress files or directories, which can prevent writing or executing necessary files.
- Solutions:
- Set the correct permissions:
- Directories: 755
- Files: 644
- Use the FTP or SSH to change permissions if needed.
3. PHP and MySQL Compatibility
WordPress requires specific versions of PHP and MySQL to function correctly:
- Causes: Outdated or incompatible PHP or MySQL versions with WordPress requirements.
- Solutions:
- Check your server's PHP version. WordPress supports PHP 5.6.20+ or PHP 7+.
- MySQL version should be 5.0+.
- Update or change your hosting environment if necessary.
The .htaccess file can cause installation problems if it's not properly configured:
- Causes: Incorrect rules or corruption in the .htaccess file.
- Solutions:
- Try renaming the .htaccess file to see if it resolves the issue, then WordPress might regenerate a new one.
- Manually update or replace the file with default WordPress rules.
5. Server Configuration
