explode() PHP error message occurs in the subtheme config settings when using PHP 8.1.
Steps to reproduce
- Launch a local site using PHP 8.1.
- Create a subtheme using bootstrap5 config settings.
- Install the subtheme.
- Go to the subtheme settings.
- The error message will appear.
Proposed resolution
Use the null coalescing operator, introduced in PHP 7, to default the value to an empty string if the value is null.
