The most common way to solve CAPTCHA is to refresh the page. This will reload the CAPTCHA and give you a new one to solve. You can also clear your browser cache and cookies, resolving issues caused by outdated data. If you're having trouble with the CAPTCHA in one browser, try using a different one. Finally, make sure you're entering the CAPTCHA characters correctly. Pay attention to uppercase and lowercase letters, as well as numbers and symbols.
