Avada 5.3 triggers PHP warning Undefined offset: 1

Symptoms

With Layouts or Views active, visit a page on the front end designed with Avada page builder and you’ll get this PHP Warning:


PHP Notice: Undefined offset: 1 in /Users/nigelanderson/OnTheGo/Sites/t-avada/wp-content/plugins/wp-views/vendor/toolset/toolset-theme-settings/compatibility-modules/controllers/toolset-theme-integration-settings-front-end-controller-avada.php on line 104


Workaround

A permanent fix for this will be released in a coming version of Views or Layouts. In the meantime, this patch can be used.

To apply it, you need to upload the content of the ZIP file to replace the existing one located in /vendor/toolset/toolset-theme-settings/, in Views and Layouts, depending on which Toolset plugins you are using.
