Start with the shortest safe check.

Start here

1. Reload once.Use a normal reload before clearing any saved progress.
2. Confirm JavaScript is enabled.The public course pages remain readable without it, but the interactive workspace requires it.
3. Try a current browser.Use an up-to-date Chrome, Edge, Firefox, or Safari window without an aggressive script blocker.
4. Keep the exact course and lesson URL.It gives support the most useful starting context without sending command history.

Loading or blank screen

Open the public course page first. If that works but a lesson does not, reload the lesson once and check whether a browser extension blocked local scripts or storage.

Do not repeatedly clear storage. It can remove progress that exists only on this device.

Progress is not saving

Keep the tab open, return to the lesson, and look for the workspace save status. If it reports a failure, export the workspace recovery file before changing browser storage.

A proof can pass while a save fails. Preserve the exact message so support can distinguish those states.

Purchase and receipt help

Use the email on your Lemon Squeezy receipt. A different email cannot read the paid entitlement.

Waitlist and updates

Course update messages include an unsubscribe path. The repository does not provide a public support email, so this page does not invent one.

Paid learner support

Sign in with the receipt email before the private support desk loads account records or existing threads.

Open paid support desk

If account access is unavailable, use the contact path printed on the payment receipt.
