			0 ignored issues – show Bug introduced 2019-06-24 17:35 UTC by Report Bug Copy Issue Report The class `Automattic\Jetpack\Analyzer\Error` does not exist. Did you forget a USE statement, or did you not list all dependencies? Scrutinizer analyzes your `composer.json`/`composer.lock` file if available to determine the classes, and functions that are defined by your dependencies. It seems like the listed class was neither found in your dependencies, nor was it found in the analyzed files in your repository. If you are using some other form of dependency management, you might want to disable this analysis. Loading history...

			0 ignored issues – show Unused Code introduced 2019-06-22 03:13 UTC by Report Bug Copy Issue Report `$ast` is not used, you could remove the assignment. This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently. $myVar = 'Value'; $higher = false; if (rand(1, 6) > 3) { $higher = true; } else { $higher = false; } Both the `$myVar` assignment in line 1 and the `$higher` assignment in line 2 are dead. The first because `$myVar` is never used and the second because `$higher` is always overwritten for every possible time line. Loading history...
