Troubleshooting WordPress and Other CMS Print

Introduction

Content Management Systems (CMS) like WordPress, Joomla, and Drupal are powerful tools for managing websites, but they can encounter issues ranging from configuration errors to compatibility conflicts. This guide provides a systematic approach to troubleshooting and resolving common issues in WordPress and other CMS platforms hosted on DomainIndia.com shared or reseller hosting.

1. Understand the Issue

Start by gathering detailed information about the problem:

• Error Messages: Ask for screenshots or the exact error message displayed.
• Recent Changes: Inquire if plugins, themes, or settings were recently updated.
• Scope: Determine if the issue is isolated to a specific CMS or affects the entire hosting account.

2. Common Troubleshooting Steps for All CMS

These initial steps apply to most CMS platforms:

2.1 Check Hosting Environment

• Ensure the hosting account has sufficient disk space, bandwidth, and inodes.
• Confirm the domain and DNS settings are configured correctly.
• Verify the PHP version and required extensions match the CMS’s requirements.

2.2 File and Directory Permissions

• Directories: Set permissions to 755.
• Files: Set permissions to 644.

2.3 Inspect Logs

• Access error logs via cPanel or use debugging tools like enabling WP_DEBUG in WordPress, or checking logs for Joomla (logs/ directory) and Drupal (/sites/default/files/).
