Error- Read/write permissions of the mmoconnector module enabled

We cant seem to get around this issue that no matter what we try on the Bigbuy Multi-channel platform – it fails to go to the next step saying: Read/write permissions of the mmoconnector module enabled (it shows a big red X)

We cant see such a module (MMOConnector) anywhere, but have made permissions changes (even to 777) in the plugin folder. We have checked other API calls on the site and they work, and the plugin shows all minimum checks are complete and successful.

Has anyone had problems with the read/write permissions on the plugin or know of any folders permissions adjustments that have to be done ?
