Unable to access WordPress with error message regarding functions.php

Hi,

I am unable to access WordPress after trying to add the Enable Avia Layout Builder Debug code to the functions.php file.

I believe that I incorrectly added it to the end, instead of after the line:
if(isset($avia_config[‘use_child_theme_functions_only’])) return;

(as per the instructions on http://kriesi.at/documentation/enfold/enable-advanced-layout-builder-debug/)

I now receive this error message:

Parse error: syntax error, unexpected end of file in /home/content/p3pnexwpnas04_data02/78/2912178/html/wp-content/themes/enfold/functions.php on line 525

I am unable to access anything within WordPress as a result. This includes the ability to remove the code from functions.php

I’m therefore unable to generate a new password, however the last generated password from a previous ticket with login details is included below.

Please can you let me know how I am able to fix this.

Thank you.
