Bug Report
Background
As I keep updating and improving the algorithm tutorials, the website and its plugins have become richer in features, but also more complex. This can cause bugs sometimes.
So, I need your feedback to fix problems quickly and give you a better experience.
Most problems are caused by old content in your local cache. Before you report a problem, please check the list of common problems below to see if there is already a solution.
Common Problems on This Site
After buying a site subscription, solutions in the plugin are still locked?
You need to manually refresh data in the plugin to unlock the solutions. Please check the Chrome plugin guide, VSCode plugin guide, and JetBrains plugin guide for detailed steps.
Error when logging in: Only overseas IP can use GitHub/Google login
Due to network reasons, the site checks your IP when logging in. Only overseas IPs can use GitHub/Google login. Users in China should log in with WeChat.
If needed, you can link more login methods on the User Profile page.
Page is stuck or not loading?
This is usually a network issue. Overseas users or users using overseas proxies might see this sometimes.
Because the site updates often, sometimes old resources are cached in your browser or CDN, causing some pages to not load.
Solution: Try clearing your browser cache and refresh the page. If it still does not work, try using your browser's incognito mode or change your network to see if the problem is local.
If you are using a network proxy, please turn off the proxy for this site, or remove labuladong.online
from the proxy rules. This should solve the problem.
Can't find results in the top right search bar?
This is usually a network problem too. The solution is the same as above.
Subscription content keeps loading but never appears?
This is usually a network problem too. The solution is the same as above.
Visualization panel is always black?
This is usually a network problem and the latest resources are not loaded. The solution is the same as above.
If you still cannot solve your problem, please report it to me.
