Major League Baseball’s website is currently experiencing technical difficulties due to issues with Cloudflare, a cybersecurity company. The problem started when the site prompted users for a security verification check, which has left many fans unable to access the official MLB website (www.mlb.com). In order to resolve the issue, users are advised to enable JavaScript and cookies on their device.
