Problem editing class-avia-combo widget.php

I modify the code in enfold/framework/php/widgets/widget-classes/class-avia-combo.php to change the appearance of the Combo Widget.

I have just updated my test server to Enfold 5.6.4 from 5.5

The first edit I do is to the popular / recent / comments code block starting at line 176.

I add this code into the ‘popular’ section:

	'cat'	=> '-1,-31,-73,-89,-708',
	'meta_key' => 'wpb_post_views_count', 
	'orderby' => 'meta_value_num',
	'date_query' => array( array( 'after' => '-1 week' ) )

after line 180, first adding a comma after
'order' => 'desc'

Now this happens when I edit the file in Dreamweaver.

I add the comma on line 180, hit enter for a new line to allow me to paste my code in, and get this error message in Dreamweaver:
“There is a syntax error on line 431. Code hinting may not work until you fix this error.”
I haven’t yet pasted my code in, all I did was add a new empty line – but as soon as I do, I get the error.

If I delete the new line and comma, the error remains (but now stating on line 430 because I’ve removed the new line). If I do add the 4 lines of code at the new line, the error message changes to line 434.

I also add a line of code into the ‘recent’ code block after line 192. If I try to make this edit first instead of the ‘popular’ edit, the same error is reported from line 431 when I hit enter for a new line.

Line 430 is the function get_post_list – but I have not been anywhere near that code. I note that Gunter made changes to the function in 5.6 and 5.6.1

Any idea what the problem is to cause this error when I edit line 180? I’ve been modifying this file for years without problems.
