edit

The warning "Array to string conversion in PHP 8.2" in WordPress means that there has been an attempt to convert an array to a string, which is not possible in PHP 8.2. This can happen when a PHP function or operation is called with an array as an argument, but the function or operation expects a string. It is important to check the code and ensure that the correct data types are being used to avoid errors in the future.
