Hello Support Team!
On the blog post pages in the comment area, once you enter your msg and forgot to enter other required fields there is a redirect to an error msg which is a bit unusual. I would rather expect to receive a small notification right near the comment area prompting to fill in other required fields, without a redirect. Is it sth wrong with Jevelin? See screenshots attached.
I hope you are well today and thank you for your question.
This is not Jevelin specific but WordPress functionality that will also work the same with any default WordPress themes.
If you want to change this behaviour then you have to develop custom code as described on the below pages.
