FACEBOOK SHARING DEBUGGER: “Can’t validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.”
Hello to everyone. Actually, I have two issues with my website. First, I’m not sure why, but it’s opening quite slowly; perhaps it’s just my browser, and I’m at a loss for what to do about it. Could you please verify it for me and give me some suggestions? Thanks! The second issue is that Facebook isn’t showing me the thumbnails for my website (created using Yoast Seo), and when I verify the link on Facebook Sharing Debugger, I get this warning “Can’t validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.”… Have you any ideas? Thank you once more!
Extra: I don’t use cloudfire and i use Let’s Encrypt SSL
Hello, and thank you for your prompt response.
I’m sorry, but I’m not the top website builder genius, and I’m working with online tutorials on my website, so I’m not sure what CA chains are. Do you think it’s important? Should I try to solve the problem or just ignore it?
Anyway, I’m using WordPress; do you think disabling wp-cron.php will solve the problem for good?
Okay, I’ve read the FAQs about the security system; is there any other way to have thumbnails? Maybe using a secondary website/service?
Okay, I’m following your responses. CA chains are being ignored. I disabled WP-cron by following the instructions at LINK HERE. However, as stated on this website and many others, it is preferable to set a Cron Job from your control panel. What are your thoughts? Will I do it? If so, I’ve tried a few things, but I’m not sure which code to use for InfinityFree!
Good day to everyone. I’ve been testing the website for a week now, and unfortunately, the opening is still very slow; do you have any suggestions for a solution? It feels like there is a significant lag at first, as if something is halting it, and then it becomes much faster.
