# Error: You have to set write permissions - Amazon Marketplace Plus

If you see one of the following messages:

||| You have to set write permissions to the /var/www/modules/amazon/export directory

or

||| You must grant write permissions to the directory: xxx/yyy


This means the Amazon Marketplace module cannot write to certain folders.

## How to Fix This

1. **Connect to your server via FTP** using a client like FileZilla.
2. **Navigate to the module’s folder**: `/modules/amazon`

4. **Enable full write permissions** (read, write, execute):

5. Click **OK** to apply the changes.

6. **Repeat the process for the following folders**:
* `validate/xsd`
* `import`
* `export`
* `settings`
* and all their subfolders and files

> ⚠️ Important: Do this only for data folders (validate/xsd, import, export, settings). Do **not** change permissions on folders containing PHP files, as some hosting providers may require stricter permissions for security.
