I've installed CComment Core on my Joomla 4 site. Looks good so far, except for one thing I don't like: The text "You are not authorised to post comments." appears above the heading "Comment". I'd rather have this below. So I tried with a template override. As per CComment documentation, I made a copy of file:

joomladirectory/components/com_comment/templates/default/default_form.php

to newly create directory:

joomladirectory/templates/my_template/html/com_comment/templates/default_form.php

and made a simple adjustment (echo "blabla". Unfortunately, this change is not seen when I display an article. Should this work? Is there a better was to get this "not aurhorized" line displayed *after* the Comment heading?

Being a Joomla newbie, this is my first override. So, I may as well have done a simple mistake.

Thanks,
Peter
