The module displays an error message :

You have to set write permissions to the /var/wwww/prestashop/modules/amazon/export directory

This is often due to a problem of permissions, folder and files write rights of the module.

It must be verified that the module has the write permission in the export directory.

Use your favorite FTP client, such as FileZilla

1. Log on to your server, go to the module’s directory, prestashop/modules/amazon:

filezilla 1 - en

2. Edit the attributes of the “export” folder, you can access this menu by positioning the cursor on the folder and clicking the right mouse button:

filezilla 2 - en

 

3. Select all the write permissions:

filezilla 3- en

 

And apply by clicking OK, the issue should be solved.

Repeat the operation for directories : validate/xsd, import, export, settings and all its sub-directories.

Notice: Do this only on data folders (Validate/xsd, import, export, settings), not on folders containing PHP files, in fact, depending on the host these other directories may require special permissions.
