I was trying to install the Elementor plugin and kept getting this error: Installation failed: The package could not be installed. Missing archive file. And sometimes: Installation failed: Could not copy file. Here's the quick copy code: define('WP_TEMP_DIR', dirname(__FILE__) . '/wp-content/uploads/'); Here's ChatGPT's full response: The error Installation failed: Could not copy file elementor/includes/widgets/traits/button-trait.php usually indicates a file permission issue or a problem with the file system during the plugin installation process in WordPress. Here’s how to troubleshoot and resolve the issue: 1. Check File Permissions Ensure your WordPress directory has the correct file and folder permissions: Folders: Should be set to 755 Files: Should be set to 644 To fix permissions: Access your site using FTP or through the file manager in your Hostinger control panel. Navigate to your WordPress installation folder. Adjust the permissions using your FTP client or control panel tools. 2. Verify Disk Space Make sure your hosting account has enough disk space available. If storage is full, WordPress may fail to copy plugin files. Check this via Hostinger’s control panel. 3. Temporary File Upload Directory Ensure the temporary folder WordPress uses (/wp-content/uploads/) is writable: Go to wp-config.php in your root WordPress directory. Add the following line if it doesn’t exist: php Copy code define('WP_TEMP_DIR', dirname(__FILE__) . '/wp-content/uploads/'); 4. Increase PHP Limits Increase PHP limits to ensure the plugin can install properly: Access your Hostinger control panel. Navigate to PHP Configuration. Increase: upload_max_filesize to at least 10M. post_max_size to at least 10M. max_execution_time to 300. 5. Manually Install the Plugin If the issue persists, manually install the Elementor plugin: Download the plugin ZIP file from the WordPress repository: Elementor. Extract the ZIP file on your computer. Upload the extracted folder to the /wp-content/plugins/ directory via FTP or Hostinger’s file manager. Go to your WordPress admin dashboard, navigate to Plugins, and activate Elementor. 6. Check Hostinger Error Logs Hostinger provides error logs in the control panel. Review these logs for additional clues if none of the above solutions work.
