Bug Report

Background

As I keep updating the algorithm tutorials, the site and related plugins are getting more features, but also more complex. This means bugs can appear.

So I need to get your feedback in time to fix problems quickly and make sure you have a good experience.

Most problems happen because local cache stores old content. Before you send feedback, please check the list of common problems below. Maybe you can find a solution there.

Common Questions About the Site

After buying the site subscription, why are the solutions in the plugin still locked?

You need to refresh the data in the plugin to unlock the solutions. Check the instructions in Chrome Extension Guide, VSCode Extension Guide, and JetBrains Extension Guide.

Because of network limits, the site checks your IP when you log in. Only overseas IPs can use GitHub/Google login.

If you use a network proxy, please set the proxy to global mode so that the domain labuladong.online goes through the proxy. Then refresh the page a few times. You should be able to use GitHub/Google login.

You can also bind other login methods on the User Profile page.

The page freezes or cannot load?

Usually, this is a network problem. The site updates often, and sometimes old cache or CDN cache causes some pages not to load.

Solution: Try clearing your browser cache and refreshing the page. If it still doesn't work, switch to incognito mode or try a different network to see if it's your local environment.

For users with network proxy, close the proxy for this site, or remove labuladong.online from proxy rules.

The search bar at the top right finds nothing?

This is also usually a network problem. Solution is the same as above.

The site subscription content keeps loading but never shows?

This is also usually a network problem. Solution is the same as above.

The visualization panel is always black?

This is also a network problem, and the solution is the same as above.

If you still can't solve the problem, please contact me for help.
