Upgrade to Wordpress 6.8.1 and plugin gives error

I upgraded to Wordpress 6.8.1 and I received an email alerting that one of my themes (Houzez) is giving error on line 555 of the file.
My website presents when Maintenance is ON, but when OFF, it does not present at all…HELP!!

Enable Debug Mode to see exactly what’s failing:

  • Edit wp-config.php and change/add these lines:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
  • Visit your site again (with Maintenance Mode off), then check:
  • The wp-content/debug.log file for the exact error message.

This will tell you which file and what code is breaking on line 555.

Thank you for your help, but I’m not sure how to identify and rectify the problem. Here is a log:
Any help appreciated:

Make sure you’re using the latest version of the Houzez Studio plugin

Hi, I’ve downloaded the latest Houzez Theme but my wordpress will not allow me to add the theme… after attaching the .zip file and clicking ‘Install Now’ I keep getting an error :‘ the link you followed has expired’.

Also have another error, Realtyna MLS Sync Error : There is no supported Theme/Plugin

HELP… our business website has been down for over 4 days now!!

Have you reached out to the theme authors?

I was sent a .zip of the latest version of the Houzez theme but haven’t contacted the author directly. Have installed Anydesk now… what do I do

The author is responding to item comments very quickly and over the weekend so you could try there https://themeforest.net/item/houzez-real-estate-wordpress-theme/15752549/comments or (assuming you still have active support) you can submit a ticket there. https://themeforest.net/item/houzez-real-estate-wordpress-theme/15752549/support

This is a theme specific question so only they will be right to help try and resolve it.

Thank you.
