Captcha is a verification system that helps distinguish humans from robots on websites. It involves entering distorted letters and numbers that appear on an image. Its purpose is to protect websites against spam, computer attacks or fraud attempts.
But sometimes the captcha does not work properly and may display an error message: invalid captcha . This can be very frustrating and prevent you from accessing certain online services or content. What to do in this case? How to solve the invalid captcha problem ? Here are some solutions to try.
1. Reload the page
The first thing to do when you encounter an invalid captcha problem is to reload the web page where you need to enter the code. Indeed, the captcha may have expired after a few minutes and is no longer valid. You won't see a warning that it is invalid. If it is not accepted, the problem may not be with your reading or typing, the code may simply have expired. Try reloading the page to get a new code , then fill out and submit the form immediately.
2. Pay attention to ambiguous characters
Sometimes the captcha is difficult to read because of the ambiguous characters that may look similar . For example, it may be difficult to tell the difference between a lowercase l I ”, or a number “ 1 ”. Likewise, it can be complicated to distinguish a capital O 0 ”. If you've tried the letter O or the number zero and it doesn't come through, try the other option.
Other characters can be confused because of the squiggles around them . For example, a “ c ” might look like an “ o ,” an “ o ” might look like an “ a ,” or a “ 6 ” might look like an “ 8. ” Try to look at the image carefully and try different possibilities if you are unsure.
3. Respect case
Some captchas are case sensitive, meaning they differentiate between upper and lower case letters. If this is the case, you must respect the case of the code displayed in the image. For example, if you see “ aBcD ,” you would enter the exact same letters in upper and lower case.
If you are not sure whether the captcha is case sensitive or not, try to respect the default case. If that doesn't work, try making everything upper or lower case.
4. Check your internet connection
Another problem that can cause an invalid captcha is an internet connection that is too slow or unstable. Indeed, if your connection is poor, the captcha may not load correctly or your response may not be sent correctly to the website server.
To check your internet connection , you can use a site like Speedtest which measures your speed. If your connection is too slow or unstable, try restarting your modem or changing networks (Wi-Fi, 4G, etc.).
5. Clear your browser’s cache and cookies
If the invalid captcha problem persists, it may be the fault of your browser's cache or cookies. The cache is a storage space that keeps data from the websites you visit to load them more quickly. Cookies are files that save your preferences and login information on websites. Sometimes this data can be corrupted or outdated and prevent the captcha from working properly.
To clear your browser's cache and cookies, you can follow these steps depending on the browser you are using:
For Google Chrome
- Click the three dots at the top right, then click Settings.
- In the search bar, type “clear browsing data”.
- Click the Clear browsing data button.
- Check the “Cookies and other site data” and “Cached images and files” boxes.
- Choose the period “All periods” then click on Clear data.
For Firefox
- Click the three bars at the top right, then click Options.
- In the left menu, click Privacy & Security.
- In the Cookies and site data section, click the Clear data button.
- Check the boxes “Cookies and site data” and “Cached web content”.
- Click Clear.
For Microsoft Edge
- Click the three dots at the top right, then click Settings.
- In the left menu, click Privacy, Search & Services.
- In the Clear browsing data section, click the Choose what to clear button.
- Check the “Cookies and other site data” and “Cached images and files” boxes.
- Choose the period “All periods” then click Clear now.
6. Disable extensions or software that blocks ads
Another possible cause of the invalid captcha problem is the use of extensions or software that blocks ads or scripts on websites. These tools aim to protect your privacy and improve your browsing experience by eliminating unwanted or intrusive elements. However, they can also interfere with the functioning of the captcha and prevent it from displaying or validating correctly.
To fix this problem, you can try temporarily disabling these extensions or software when you need to enter a captcha. For example, if you use AdBlock or uBlock Origin, you can click their icon in your browser toolbar and choose Disable for this site or Pause. If you use software like Malwarebytes or Avast, you can temporarily disable it in its settings.
7. Use a different browser or device
If none of the above solutions work, the problem may be with your browser or device. There may be a bug, incompatibility or setting that prevents the captcha from working correctly. In this case, you can try using another browser (Chrome, Firefox, Edge, etc.) or another device (computer, tablet, smartphone) to access the website where you need to enter the captcha.
This may allow you to work around the issue and check if the captcha is working correctly elsewhere. If so, then the problem is indeed with your original browser or device and you may need to update, reset, or repair it.8. Contact website support
Finally, if all the solutions mentioned above do not resolve the invalid captcha problem, the problem may come from the website itself . There may be a malfunction , maintenance or breakdown that affects the captcha and prevents users from using it correctly.
In this case, you can try contacting the website support to report the problem and ask them for help. You can usually find support contact details on the website itself, under Contact, Help or FAQ. You will need to tell them your email address, the subject of your request, the website concerned and the problem encountered. You will then receive a response by email as soon as possible.
