Common Plugin Issues

Common issues and solutions for plugins are introduced in their respective documentation. See Chrome Plugin Documentation, VSCode Plugin Documentation, and JetBrains Plugin Documentation for details.

Common Site Issues

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

To unlock the solutions in the plugin, you need to manually refresh the data. Please refer to the instructions in the Chrome Plugin Documentation, VSCode Plugin Documentation, and JetBrains Plugin Documentation.

Error message during login: "Only overseas IPs can use GitHub login"

Due to network restrictions, IP verification is required during login. Only overseas IPs are supported for GitHub login. Users in China should use WeChat login.

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

1. During login, use a non-mainland China IP address to log in with GitHub.

2. Transfer your order to your WeChat account. Email labuladong@foxmail.com with a screenshot of your payment and the user ID of your target account (WeChat login account), and the support team will help transfer your order.

Page freezes or fails to load?

This is usually a network issue and may occasionally occur for overseas readers or users with overseas proxies.

Since the site is updated frequently, local or CDN cache may sometimes prevent the latest resources from loading, causing some pages to be inaccessible.

Solution: Please try clearing your browser cache and refresh the page. If the problem persists, try using incognito mode or switching networks to determine if the issue is local.

If you use a network proxy, try disabling the proxy for this site, or remove labuladong.online from the proxy rules to avoid such issues.

This is usually a network issue as well. The solution is the same as above.

Membership content keeps loading and never appears?

This is usually a network issue as well. The solution is the same as above.

Visualization panel remains black?

This is usually a network issue, causing the latest resources to not load. The solution is the same as above.

If your issue is still not resolved, please contact us for support.
