Troubleshooting the Destination folder already exists error in WordPress

Whether you are a full beginner or a WordPress expert, these troubleshooting will save you a ton of time. Always remember to back up your WordPress site before making any changes to the file structure.

Troubleshooting tips

The easiest way to fix this error is to delete the plugin or theme folder that caused it. This can be accomplished through the WordPress admin dashboard or via FTP or CPANEL. You must clear your cache and reinstall the plugin or theme afterward.

Method 1: Fix via the WordPress Dashboard

In order to install a plugin or theme manually, WordPress extracts the .zip file to a folder of the same name. WordPress will display a comparison between two identical folders with the same path if it detects an identical folder.

When this happens, WordPress asks for permission to overwrite the old plugin or theme folder. You should be able to resolve the “Destination Folder Already Exists” error message by selecting “Replace current with uploaded”.

  1. Go to your WordPress Dashboard.
  2. Navigate to Plugins > Add New.
  3. Upload the zip file of the plugin or theme.
  4. Select Replace current with uploaded to overwrite the existing folder.
Destination folder already exists. The plugin is already installed.

This warning only appears when you are installing a .zip file.

Method 2: Fix Using FTP to Solve the Destination Folder Already Exists Error

If the WordPress dashboard method doesn’t work or isn’t available, FTP (File Transfer Protocol) is your next best friend. Follow these steps:

  1. Connect to your server using FTP credentials.
  2. Navigate to the root WordPress directory.
  3. Go to wp-content/plugins or wp-content/themes, based on whether you are installing a plugin or a theme.
  4. Locate the folder causing the error (most likely the folder name is identical to the plugin or theme).
  5. Right-click and delete the folder.
  6. Clear your WordPress cache.
  7. Reinstall the plugin or theme.
