In trouble-shooting an issue with the Pre-SQLs, I noticed that in yii2-reportico/components/reportico.php there are several syntax errors, mostly undefined variables. See lines 4660, 5247, 6374, 6966, 6979, 6990, 8320, 8541.
The last Git update was 4.6, 3 years ago. Are you no longer maintaining this Yii2 plug-in?
