Login problem (Button ‘login’ not responding)

Hello

I have already posted in 3 different forums of WP, and each time got directed to another forum. I hope this time I’m in the right place to solve the issue I have with the login to my admins area.

Here is the description:

I cannot access my admins area. when I click the “Log-in” button nothing happens… the button doesn’t respond to my request to login.
I don’t receive any “error message” or “error password”, it just stays on the login page without entering the admin area.

I tried to solve this issue and I received this answer / info (not in the forum):

“…This is related to an issue establishing a captcha for the login page which is preventing it from doing anything else. So it looks like one of the plugins on your website has caused an issue that is preventing you from logging into your site…. To regain access to the administration area you will need to disable whichever plugin is causing the problem…. Once all plugins are disabled you will be able to access your administration area again and then you can re-active all plugins except for the one that broke your login form.”

The plugin that is installed on my website for login is: ‘Colorlib Login Customizer’.
I already disactivated this plugin, but still could not login.

Does anyone familiar with that issue and can give me a clear guidance?

Thank you in advance !`
