Invalid argument supplied for foreach() error

[Had]

Hi

I have got some error message lately:
Warning: Invalid argument supplied for foreach() in /data/web/virtuals/137107/virtual/www/domains/halove-centrum.cz/haatto/wp-content/plugins/cornerstone/includes/utility/element-api.php on line 210

http://halove-centrum.cz/domains/halove-centrum.cz/haatto/

How can I fix it?

Regards
Dan

Hey Dan,

That could be a result of version incompatibility between an old version of X and a new version of Cornerstone or vice versa. Always, ensure everything is up to date according to our version compatibility list at https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195. Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.

It’s also a best practice to disable the display of errors in a live site. You can disable the error display by following the debugging documentation of WordPress here: https://wordpress.org/support/article/debugging-in-wordpress/

You can follow the example setup but please try to understand what each line of WordPress configuration does.

Thanks.

Hey Dan,

To obtain Cornerstone please follow the Manual Update section here https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 and then you can update Cornerstone via FTP by following the steps mentioned under Manual Plugin Update Via FTP in the same link shared above.

Hope this helps!
