How to Troubleshoot ‘Unable to Update Files’ on WordPress Theme Editor

When using WordPress, you might occasionally face challenges when trying to update your theme files through the Theme Editor. This guide will help you resolve the issues that prevent you from accessing or updating your files within the Theme Editor. Common causes and solutions will be discussed, including how to uncheck the ‘Disable File Editor’ box if you are using iThemes Security or similar settings if you are using another security plugin.

Why Can't I Update My Files on the Theme Editor?

One of the potentially frustrating issues you may encounter is the disappearance of your Theme Editor from the Appearance tab on your WordPress Dashboard. This can happen after updating your WordPress Security plugin to iThemes Security (formerly Better WP Security), which may have a default setting to disable the file editor. Here are the steps to fix this problem:

Steps to Resolve the Issue with iThemes Security

1. **Access Your WordPress Dashboard**: Log in to your WordPress Dashboard.

2. **Navigate to Plugins**: Go to the Plugins section, find the Themes or Plugins sidebar, and click on Active Plugins.

3. **Locate iThemes Security**: Look for the iThemes Security plugin. Click on the Settings link for this plugin.

4. **Check ‘Wordpress Tweaks’**: Scroll down to the Wordpress Tweaks section and find the option labeled File Editor.

5. **Uncheck ‘Disable File Editor’**: Ensure that the box next to Disable File Editor is unchecked. This will enable the Theme Editor again.

Steps if You Are Using Another Security Plugin

If you are not using iThemes Security, you may have a similar setting in another security plugin that is causing the issue.

1. **Identify Similar Setting**: Check the settings of your current security plugin to find any similar settings that could be disabling the file editor.

2. **Disable the Setting**: Switch off or update the setting to allow the file editor functionality.

Common Causes and Additional Solutions

Aside from the security plugin settings, there are other potential causes for the ‘Unable to Update Files’ issue. These may include missing MySQL entries or errors in PHP files. In such cases, you may need to use alternative methods like SFTP to update your files:

Using SFTP to Update Files

1. **Access Your Hosting Via SFTP**: Use an SFTP client (such as FileZilla) to access your hosting server.

2. **Locate Theme Files**: Navigate to the appropriate directory where your theme files are stored (usually under /wp-content/themes).

3. **Upload Modified Files**: Upload the updated PHP file using SFTP to replace the original file.

Conclusion

By following these steps, you should be able to resolve the issue of being unable to update files on the Theme Editor of your WordPress site. Always ensure you have backups of your files before making any changes, and if you encounter persistent issues, don't hesitate to reach out to your hosting provider.
