i'm using version 4.5.8 on WP 5.2.2. Uninstall and re-install of the plugin didn't work

Hi,

Thanks for contacting us here about this extension.

Any ideas why I just see a blank screen when accessing the admin panel?

First, you need to clear your cache. If it still remains the issue, please drop us a ticket (menu Support > Ticket support).
Our developer in charge will take a look at that.

Thanks a lot!
Cheers,
