Background

As I continue to iterate on the algorithm tutorials, the site and its associated plugins have become richer in features, but also more complex, which inevitably leads to bugs.

Therefore, I need to promptly receive feedback on issues and quickly fix them to avoid providing a poor user experience.

Most issues may be caused by cached outdated content locally, so please check the following common issues list before providing feedback to see if there is a solution.

Feedback via Email/WeChat

For issues directly affecting usage such as payments, permissions, or site availability, you can provide feedback through email or WeChat for immediate handling:

Email: labuladong@foxmail.com
WeChat: Only supports paid subscribers. You can add my WeChat or join the site's WeChat discussion group on the Site Subscription page.

Please describe your issue in detail, preferably with screenshots and error messages. For payment/permission issues, include your User ID and order number.

Feedback via GitHub Issues

Any bugs, feature suggestions, or other feedback regarding the website and related tools can be submitted through GitHub Issues. This allows other readers to view and discuss them.

When submitting an Issue, please keep the following points in mind:

Before submitting an Issue, you can search to see if others have encountered similar problems and if there are already solutions available.

Each article on this site has a comment section at the bottom. For non-urgent issues like typos or small code bugs, you can directly leave a comment in the comment section. I will check and address the comments regularly.

Common Plugin Issues

Common issues and solutions for plugins are described in the usage instructions for each plugin. See Chrome Plugin Instructions, VSCode Plugin Instructions, JetBrains Plugin Instructions.

Common Site Issues

Why are solutions in the plugin still locked after purchasing a site subscription?

Solutions in the plugin require manual data refresh to unlock. Refer to the detailed operation method in Website Subscription.

Due to network reasons, IP verification is conducted during login. Only overseas IPs can use GitHub login. Domestic users should use WeChat login.

If you have already purchased a site subscription using a GitHub account, there are two solutions:

If you are logging in with a non-mainland China IP address, you can use GitHub for login.
Transfer the order to a WeChat account. Email labuladong@foxmail.com, provide a payment receipt screenshot, and the WeChat login Account ID, and we will assist in transferring the order.

Can't find content in the top-right search bar?

Most likely a network issue. Please disable network proxies or try again after changing networks.

Page freezing/loading issues?

This is usually a network issue. Overseas readers and those using overseas proxies may occasionally encounter this.

Due to frequent site updates, if local or CDN caching prevents the latest resources from loading, some pages might become inaccessible.

Solution: Try clearing browser cache and refreshing the page. If the issue persists, try changing networks to verify if it's a client network issue.

For domestic readers using overseas proxies, disable the proxy when accessing the site, or remove labuladong.online from proxy rules to avoid such issues.

If the problem continues, please provide feedback.

Why is the site subscription content endlessly loading?

This is typically a network issue, with the same solution as above.

Why is the visualization panel black?

This is often a network issue, preventing the latest resources from loading, with the same solution as above.
