With php 7.2 I got the same error:

Fatal error: Uncaught Error: Call to undefined function avia_is_burger_menu() in /home/infovisti/public_html/wp-content/themes/enfold/header.php:32 Stack trace: #0 /home/infovisti/public_html/wp-includes/template.php(688): require_once() #1 /home/infovisti/public_html/wp-includes/template.php(647): load_template(‘/home/infovisti…’, true) #2 /home/infovisti/public_html/wp-includes/general-template.php(41): locate_template(Array, true) #3 /home/infovisti/public_html/wp-content/themes/enfold/page.php(9): get_header() #4 /home/infovisti/public_html/wp-includes/template-loader.php(74): include(‘/home/infovisti…’) #5 /home/infovisti/public_html/wp-blog-header.php(19): require_once(‘/home/infovisti…’) #6 /home/infovisti/public_html/index.php(17): require(‘/home/infovisti…’) #7 {main} thrown in /home/infovisti/public_html/wp-content/themes/enfold/header.php on line 32

I don’t know what you mean with “clean your directory” as I just upload you theme folder on my server.. that’s it.

anyway my need to update the theme is only due to the necessity to add an API key to make the Google maps working… is there a turnaround for this?

Exactly, you can temporary switch to the new version of the theme to see what’s happen

Hi,

If you enable the Wordpess Debug you’ll see the error I’m talking about..

Hi,

I’m sorry maybe I was not enough clear to you. What I’m saying is that the error happens when I activate the new theme “enfold” that has not been modified at all.. https://www.dropbox.com/s/33ntoo3l1hndhfr/Screenshot%202018-10-10%2010.45.53.png?dl=0

the current website is using an old modified version of enfold.. and is working..

Hi,

I’ve uploaded again the Enfold folder but no changes.

Hi,
