I get the following when trying to sign into ancestry.com "pretty-print { } ".

Hi bruce lynn,

Welcome to Microsoft Q&A!

It’s definitely confusing to sign in to Ancestry.com and Edge only shows a black screen with pretty-print { } dialog. This usually means the site’s script isn’t loading correctly, often due to cached data, an extension, or rendering. Here's something you should consider:

1. Temporarily disable any active VPN software or extensions.
2. Identify whether the issue is Edge-specific, network-wide, or account-related:
   1. Try a different browser (e.g., Firefox, Edge)
   2. Use a different device on the same network
   3. Switch to a different network, like your phone data.
3. Test in InPrivate mode (Ctrl+Shift+N). This rules out extension interference, e.g., ad blockers, privacy tools, or script modifiers.
4. If the site is accessible in InPrivate, clear your browser cache and cookies to remove any outdated files that may be causing the display conflict. Open Edge and press Ctrl + Shift + Del > choose All time range and click Clear now.
5. If the issue only affects Ancestry, it may relate to an authentication error on their side. In that case, you might need to contact their support.

This issue often points to a server-side routing or regional restriction on Ancestry’s end. It essentially means the website's server is sending raw data instead of the visual page you expect to see. I hope the above suggestions can help you sign in to the site smoothly.

The issue you're experiencing with signing into ancestry.com on Microsoft Edge, where the screen remains black and displays "pretty-print { }", could be related to several factors. Here are some troubleshooting steps you can try:

1. Clear Browser Cache: Sometimes, cached data can cause display issues. Go to Edge settings and clear your browsing data.
2. Disable Extensions: Some browser extensions may interfere with website functionality. Try disabling them temporarily to see if that resolves the issue.
3. Check for Updates: Ensure that your Microsoft Edge browser is up to date. An outdated browser may have compatibility issues with certain websites.
4. Use InPrivate Browsing: Try signing in using an InPrivate window. This mode does not use cached data or extensions, which may help isolate the problem.
5. Reset Edge Settings: If the problem persists, consider resetting Edge settings to their default values. This can resolve various issues related to browser configuration.

If none of these steps work, it may be beneficial to check if the issue is specific to ancestry.com or if it occurs with other websites as well.
