Log-in to your server account using your FTP client, browse to the PrestaShop folder, and find the folders that are marked by the installer as in need of a permission change. Changing file/folder permission on a Unix/Linux system is called a "CHMOD", after the command of the same name – you can find an explanation of file permissions here). Giving them "write permission" is called "doing a CHMOD 755" or "a CHMOD 775", depending on the host – although the last one .

Some hosts might require you to use CHMOD 777, although it is not recommended for anything more than a one-time need. |
In any case, thanks to FileZilla (and most FTP clients), you can change permissions easily and graphically: once you have found a file or folder that needs such a change, right-click on it from your FTP client, and in the context menu choose "File permissions...". It will open a small window.
