Ok lets try again.

If you are getting this WARNING:

Warning: asort() expects parameter 1 to be array, null given in <span>/</span>home<span>/</span>xxx/public_html/plugins/editors-xtd/helix_shortcode/helix_shortcode.php on line 24

when you are using CB 2.0 Blogs during blog creation, it means that your are executing the helix_shortcode.php file.

I did a Google search and it looks like this is something associated with a third-party Joomla plugin called

www.joomshaper.com/documentation/joomla-extensions/helix-shortcode-generator

So it looks like this plugin is causing your warning message.
