A Cross-site scripting issue on PHP-based website

Hello, I have a tech blog site and it is a PHP-based website. But recently there is a problem on my site. A cross-site scripting issue on my tech website. I dont know why this happens. This is my website. Can experts please help me to figure out the issue? Any help would be highly appreciated.

Thanks!

Hi @Eulalia - I removed the link to your site, for it doesn’t help explain the problem. Plus, SEO crawlers wouldn’t want to index a “problematic” site.

Now, in the case that you actually have a technical problem, do post more specifics on where the issue is being flagged in.
