Parse error: website crash! help!

---

I just updated to the new version of laytheme and my website crashed. I cannot even login to the admin. I have no idea how to fix this. Can you please help?

Parse error: syntax error, unexpected '[' in /usr/home/elenagallen.com/web/wp-content/themes/lay/frontend/assets/php/row/row_functions.php on line 10

my website is www.elenagallen.com
my browser is Firefox running on MacOs High Sierra

Dear @harrietbrown
Do you have any third-party plugins installed or CUSTOM JS code? Is it possible to deactivate it for a moment to see if the problem remains?
Many wishes!

Dear @mariusjopen No, i have no custom JS codes or third party plugins as far as I know... And also, I cannot even login to the admin of wp anymore... cause the same error keeps popping up. I don't know how to login as the domain seems to have crashed when updating http://elenagallen.com/wp-admin/

pls let me know. i'm concerned.

Dear @harrietbrown
Can you login via FTP or WebFTP and rename the theme folder to laytheme_DEACTIVATED?
Then you can access Wordpress again.
Armin should have a look soon also.
Best!
