Hello...

When I tried to save com_content setting, a JavaScript alert appeared telling me to select another component.

By researching, I found the cause of the problem. At line 43 of library.comment.php, this line appears:

array_unshift( $list, JHTML::_('select.option',  '', 'com_content', 'value', 'text' ) );

I changed to

array_unshift( $list, JHTML::_('select.option',  'com_content', 'com_content', 'value', 'text' ) );

and it worked
