I solved the issue to show title field on comment form. Still the other issue.

I am not too sure what other issue are you referring to here. Can you please advise?

When user submit a comment but no insert any title i see on the comment submitted "no title". I wish see it in my language. The constant is already translated but this is still in english.

Can you provide me with the string that you translated?

I have this: COM_EASYBLOG_COMMENT_NO_TITLE="..."

Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Are you referring `No title` from backend Easyblog comment listing page? Perhaps you can take a look of my screenshot below.

If yes, you have to modify this following language string from your backend.

COM_EASYBLOG_COMMENTS_NO_TITLE="No title"

administrator\language\xx-XX\xx-XX.com_easyblog.ini <- Replace xx-XX to your current language code
