Parse error: website crash! help!

[harrietbrown]

hello again, nobody is answering to my issue but my website crashed completely after updating my lay theme. I can no longer even login into wordpress. My main website www.elenagallen.com displays this error: 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

please I need immediate help to get my site back up but since i cannot login to the admin it seems impossible..

thank you so much for your assistance.

Dear @harrietbrown

can you login via FTP and rename the folder of laytheme. Then a different theme will be activated.
Does Wordpress work then again?

Ok, thank you for writing. We will have a look also with Armin and hope to get back to you as soon as possible.
Thank you for using LayTheme!

you need to update your php version to like 7.3 in your webhost control panel
