2018年4月2日更新后WhatsApp Web无法启动及加载异常技术问询

Based on the error logs you shared:

/app.f7c554586d665fe6fd2e.js:33 Uncaught SyntaxError: Unexpected identifier
progress.54976898720da809471639fb0b654280.js:2 Uncaught TypeError: window.Exe is not a function at i (progress.54976898720da809471639fb0b654280.js:2) at HTMLScriptElement.u.onload (progress.54976898720da809471639fb0b654280.js:2)

These errors typically point to corrupted cached assets or browser configuration conflicts. Here are actionable steps to resolve this, even in incognito/private mode:

1. Clear Browser Cache and Site Data #

Corrupted cached JS files are the most likely culprit here. Follow these steps for your browser:

• Chrome: Go to Settings > Privacy and security > Clear browsing data. Select "All time" as the time range, check "Cached images and files" and "Site data", then click "Clear data".
• Firefox: Go to Settings > Privacy & Security > Cookies and Site Data > Clear Data.... Check both "Cookies and Site Data" and "Cached Web Content", then click "Clear".

After clearing, restart your browser and try loading WhatsApp Web again.

2. Disable All Extensions (Including Incognito-Enabled Ones) #

Even in incognito mode, some extensions might be set to run by default and interfere with WhatsApp Web's scripts:

• Chrome: Type chrome://extensions/ in the address bar. Toggle off all extensions, then check if incognito mode works. To verify incognito permissions, click "Details" on each extension and ensure "Allow in incognito" is unchecked.
• Firefox: Type about:addons in the address bar. Go to "Extensions" and disable all of them. For private mode access, click the three-dot menu on each extension and uncheck "Run in Private Windows".

3. Reset Browser Settings to Default #

If the above steps don't work, resetting your browser can fix hidden configuration issues:

• Chrome: Go to Settings > Advanced > Reset and clean up > Restore settings to their original defaults. Click "Reset settings" to confirm.
• Firefox: Go to Settings > General > Firefox Updates > Refresh Firefox.... Follow the prompts to reset your browser (this preserves bookmarks and passwords but removes extensions and custom settings).

4. Ensure Your Browser is Fully Updated #

Outdated browsers can have compatibility issues with the latest WhatsApp Web code:

• Chrome: Go to Settings > About Chrome—it will automatically check for updates. Restart if an update is available.
• Firefox: Go to Help > About Firefox to check for updates and install them.

5. Flush Your DNS Cache #

Sometimes DNS cache conflicts can prevent proper loading of web apps. Run these commands in your terminal/command prompt:

• Windows: Open Command Prompt as admin and run ipconfig /flushdns
• macOS: Open Terminal and run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
• Linux: Open Terminal and run sudo systemd-resolve --flush-caches

If none of these steps resolve the issue, try accessing WhatsApp Web from a different device to rule out network-level restrictions.
