Confirm the bot role, server role, channel overrides, and resource permissions match the guide.
Start here.
Most setup problems come from missing permissions, wrong file names, missing environment variables, or resources starting in the wrong order.
Check API keys, client IDs, callback URLs, category IDs, channel IDs, and webhook URLs for typos.
Make sure dependencies start before the resource or bot feature that depends on them.
Read the first real error, not just the last line. The first error usually points to the root cause.
For web UI changes, hard refresh or clear cache before assuming the deployed page is wrong.
Send the product name, error screenshot, config section, and the steps already tested.
Still stuck?
Send the exact product, server framework, error text, and what changed before the issue started.
