Hello, Good day!
I have a concern regarding this matter, verification page process does not appear every time I register a new user so I cant see the resend link button and the message that I need to verify first the email. How do I fix it?
Thank you in advance!

I can see you're using a custom form, and it's up to the form how to display success/error messages. Could you please tell me what plugin/theme is responsible for generating the form? If it's a popular one, we might add integration with our plugin.
However, We have a shortcode available called [uv_resend_verification_form] that you can use on a page for resend verification. And you can link the page wherever you think it fits, like on this error message - https://i.imgur.com/SSPzVfQ.png
Kindly check the link below for our available shortcodes and hooks.

Hi,
Welcome to PickPlugins.
Could you please share your site registration URL? Without the URL, it's impossible to figure out the issue.
Regards.
Regarding the theme, we are using Golo theme for business listings.
Thank you for your time and kind consideration. I really appreciate your help. I will check it and make some changes if possible.
