If you see this pop up but you have zilpay installed - try the following steps.
If your wallet is unlocked, it will show you your balance and transaction history. If it asks for a password, then its still locked.
Just refresh the page. Sometimes zilpay doesn't inject the blockchain connection into the browser. A refresh will fix this issue 90% of the time.
Sometimes zilpay is buggy - so lets turn it off and back on again. Its easy to do.
Step 1. Close Mintable.app - you don't need it open and it won't help if you keep mintable open.
Step 2. Right click ZilPay in your browser
Step 3: Turn this slider on and off.
Step 4: Go back to Mintable and try to do what you were doing again.
Step 1: Open Zilpay and click on the 3 lines in the top left then click "connections"
Step 2: Click the trash icon next to the Mintable.app connection
Step 3: Refresh the page on Mintable and try again.
