error 500 after update

Hi,

I’ve just updated to the latest versions of wordpress, woocommerce and also your plugin.

Now im getting the following error;

Call to a member function is_role() on null in wp-content/plugins/dc-woocommerce-multi-vendor/includes/wcmp-core-functions.php on line 858

tried downgrading a few versions of woocommerce…wasn’t that….plugin says its compatible with latest wp version so not sure if its a bug or issue with latest update?

Additional notes

Im using the plugin on a wp-network setup….i can access my main network site no problem is only when i try to access the dashboard of one of my sub sites when im logged in as master admin.

Additional question

I have the main plugin setup on my master network site….but the vendor shops will be on sub/network sites in sudirectory setup…..is there a way to have the vendor account persist across multiple network sites rather than having to register for a vendor account on each website?

Thanks in advance….GREAT PLUGIN BTW.
