Hi?@mairimweb
Could you provide more information, what reCAPTCHA plugin do you use, how your registration forms are created and what settings they have? Do you have other ways on how user can be created or registered on your website? Or maybe do you mean reCAPTCHA for the login form?
Our plugin has 200k+ active installations. 1 installation of a unique site with its own settings starting with hosting, an active theme and a different set of plugins.
We are open to solving any problems that affect our plugin, if the problem is related to other themes, plugins or themes, we can inform them about it. This is the strength and values of the community. We fulfill each request to improve security in the plugin on time. And security is a top priority for releases.
Please report your problem input using any method available to you, e.g. in this thread, on GitHub, to the WordPress Plugins Directory team, to any security plugins team like WordFence, or on the ultimatemember.com website.
I’m sorry, but without clear input of the issue it looks like we need to solve a problem that only you know. It is impossible to solve something without knowing the input.
Best Regards!
