title: Why does reCAPTCHA only show up on certain computers/browsers?
body: <p>I added the PHP reCAPTCHA to my employer's quick question form, here's a link to it: <a href="https://dept.ku.edu/~wstaff/question/quick_question.php" rel="nofollow noreferrer">https://dept.ku.edu/~wstaff/question/quick_question.php</a></p>
  
  <p>For some reason, the CAPTCHA box itself won't show up when I go to it on my work computer. This happens in Firefox, IE10, and Chrome. However, it shows up fine in Safari. I work in a library on my university's campus and when I go to the same site on a library computer, the CAPTCHA loads fine on every web browser. Could this be some sort of spam prevention due to my testing the CAPTCHA too much on my work computer?</p>
  
  <p>I had this problem in the past: <a href="https://stackoverflow.com/questions/24335705/why-does-my-php-recaptcha-only-display-on-chrome-and-safari">Why does my PHP reCAPTCHA only display on Chrome and Safari?</a> but out of nowhere the CAPTCHA started rendering again on my computer so I stopped worrying about it (dumb mistake).</p>
  
  <p>The really weird thing here is I just tried to load the page on my coworker's computer and no CAPTCHA shows up! Something to do with the network being blocked? Why would only Safari work?</p>
  
  <p>Has anyone else had this issue with reCAPTCHA? I was recommended in my previous post that it could be bad HTML syntax causing the rendering issue, and I'm in the process of cleaning up my syntax, but it doesn't make sense why all of the browsers on another computer would render the CAPTCHA fine whereas mine leaves it completely blank, i.e. the box doesn't show up at all.</p>
  
  <p>Sorry if I'm missing something obvious and for my beginner-level HTML/PHP knowledge. Also, thanks in advance for any guidance.</p>
  
  <p>Forgot to mention, I've implemented reCAPTCHA on various other forms on my employer's website, all of which still display without issues.</p>
