Sorry, you are not allowed to access this page.

I just installed this plugin and wanted to try it out.

After clicking on settings, it leads me to this page

https://dollm8.com/wp-admin/admin.php?page=wcusage_settings

but it gives me this error:

Sorry, you are not allowed to access this page.

So, I am not able to use the plugin at all.

I am using an administrator account.

Thanks!
