HTML `<meta>` Tags Not Reflecting Changes in Facebook Open Graph - Need guide Debugging
I'm sure I'm missing something obvious here, but I've been trying to set up Open Graph meta tags in my HTML for Facebook sharing, but the changes aren't reflecting when I test it with the Facebook Sharing Debugger... Specifically, I added the following tags to the `<head>` section of my page: ```html <meta property="og:title" content="My Awesome Page" /> <meta property="og:description" content="This is an awesome page that does awesome things!" /> <meta property="og:image" content="https://example.com/image.jpg" /> <meta property="og:url" content="https://example.com/awesome" /> ``` Initially, I had included the tags but they were incorrectly formatted (using `<meta name="...">` instead of `<meta property="...">`). After correcting this, I still find that the old values are being cached and displayed. I've cleared the cache on my server and also tried using the 'Scrape Again' button in the Sharing Debugger, but I keep getting the warning: "Could not extract a title, description, or image from the URL." I verified the image URL works and is publicly accessible. Additionally, I'm using the latest version of PHP on my server and I have implemented a caching mechanism using Redis. Is it possible that Redis is caching an outdated version of the meta tags? Or could there be some other scenario at play? I'm looking for any insights on how to resolve this scenario and ensure that Facebook picks up my updated Open Graph data correctly. Thanks in advance!
