What to do if the captcha on the site does not work

[subornaakter20]

Most often, captcha does not work on a site made on WordPress. Most WordPress caching plugins operate on the server side. That is, to increase the speed of the call, database requests are stored on the server side. Therefore, WordPress plugins save the structure of blocks on the page, which overloads the cache. As a result, captcha does not work correctly and even classic tests are distorted.

This issue can be resolved by replacing the captcha with server-side task generation with an AJAX captcha. With it, tasks from the server are accepted without reloading the page. Google direct moving leads email list reCAPTCHA (v2), NoCaptcha — the latest releases of Google captcha, connected using the Google Captcha (reCAPTCHA) plugin by BestWebSoft — work using this technology.

Custom Captcha Overcoming Methods
Identifying a person on a website is a simple and quick thing. But it only seems so at first glance. For users who rarely register, post messages on forums, download content, there are usually no difficulties. But for those who constantly surf the Internet, the problem of passing the captcha is quite acute.

Options for entering a web resource using captcha:

independently by the user;

other people for a fee (customers turn to special services for automatic captcha entry to speed up the registration process in conditions of time constraints);

programs that recognize text (they cost money, and their efficiency is not ideal, but some optimizers use this approach).

Robot vs. robot is a good idea, but currently imperfect, since there are services with real people to solve captchas. If software successfully entered captchas, then people would not be paid for it.

However, there are programs for entering captchas that, in principle, suit customers, and they buy them. But here we are talking most often about software written for a specific web resource using extensive knowledge of programming and php. This is especially true for recognizing captchas in Russian, for the creation of which only Russian-speaking programmers are involved, which significantly narrows the geography of IT specialists.

The most famous captcha recognition service, which is in demand, is called Antigate. Other equally famous software products are Death by captcha and DeCaptcher.

DeCaptcher

There have been many solutions put forward and discussed on how to make it so that when finding an interesting site, entering a captcha to register on it would not be necessary at all. Discussions were held, among other things, in various social networks. There were even successful finds that were described, for example, in the same VKontakte.

It was suggested to enter a special code instead of captcha to bypass it or to click on a random part of the page, but these methods did not always work and not on all sites. Usually they worked when there was an error in the code. However, vigilant programmers, especially those working on serious web resources, quickly corrected it, and this path became closed.
