Hi! I understand you're having trouble loading the Divtracker Dividend Tracker portfolio page on your Windows PC, even though it worked fine before. Let's get this sorted out together.

To start, could you let me know:
- Are you seeing any error message or just a blank page?
- Have you made any recent changes to your browser or system?
- Which browser are you using exactly? You mentioned WebKit—do you mean Safari or a WebKit-based browser on Windows?

Meanwhile, here are some simple steps to try:

1. Clear Browser Cache and Cookies
Sometimes old cached data causes loading issues. Go to your browser’s settings, find the option to clear browsing data, and remove cache and cookies. Then restart the browser and try loading the page again.

2. Try a Different Browser
If you're using a WebKit-based browser, try opening https://divtracker.app/portfolio in Chrome, Firefox, or Edge to check if the problem is browser-specific.

3. Check Internet Connection and Firewall
Ensure your internet is stable. Also, sometimes firewall or antivirus software blocks certain web pages. You might want to temporarily disable those to test if that helps.

4. Disable Browser Extensions
Some extensions like ad blockers can interfere with page loading. Try disabling extensions, especially ones related to privacy or security, then reload the page.

If these steps don’t resolve the issue, we can move to deeper diagnostics such as checking for any server-side issues, inspecting developer console errors, or possibly clearing advanced browser data.

Let me know how these go or if you see any specific errors during loading!
