Thank, Ben!
1. & 2. I’m not sure if these page settings were related to this issue specifically (and I don’t feel like testing it), but I’m glad you pointed it out, because not setting a page in the options of another plugin caused me problems in the past and it drives me crazy because if it doesn’t work without setting the page then the plugin should establish a default page for you! Or at least set up a notice that tells the admin that the page must be set for it to work properly!
3. Yep, I overlooked that setting. The disable options now work properly which supports my theory about how it’s coded. You definitely address this in the next release because those settings shouldn’t be dependent on whether you have coupons enabled on Woocommerce settings!
Thanks, again! You were very responsive and helpful!
