I work with a group of people and we all have the same issue, Here is what happens:

This is the captcha that i get (chronoforms5):

If I enter that captcha it fails, however if I open Firebug and inspect the image, this is what i see:

Now if i enter that captcha its successful, And I have this issue with virtually all of the captcha's on this website, including: RSforms, Chronoforms and Acymailing.

Any Help with this Issue would be Fantastic.

Answer 1

So in the end it was empty image tags <img src="" /> or empty background:url();. I have no Idea why. But after an entire day, I finally figured it out. Thank you all for your effort.

Answer 2

There may be a conflict between CAPTCHA and the Joomla cache.

Try temporarily disabling the cache if cache is enabled to see if this fixes the issue for you.
