My username and password ar enot accepted in the The White Label Tutorials configuration!

Hello

I have installed and activated the White Label Video Tutorials but when I try to configure and enter my username and password (which I used to install the dashboard and activate) do not stick and I keep being represented with the same login screen for this plugin.

Can you please fix my issue as I am due to hand over to the client tomorrow and this was one of my last tasks.

Regards

Bahman
