Are you trying to publish an ad with our Marktplaats WooCommerce plugin? Then you have probably encountered the following error message: ZIP code is too long and cannot be longer than 6 characters.
In this case we are referring to the ZIP code, which you have set in the settings of the plugin. You can find this via WooCommerce > Settings > Marktplaats tab.
The space in the ZIP code also counts as a character. As a result, it is seen as 7 instead of 6 characters. You can easily fix this by removing the space!
