@Marcinl4567 przecież Ci napisali w czym problem. DB Error: syntax error - czyli innymi słowy masz gdzieś babola w zapytaniu (prawdopodobnie w funkcji delete, bo to +- 150 linia)

  $sql = "DELETE FROM $tableName";
 
            $sql .= "WHERE $sWhere";

daje ci ciąg znaków "DELETE FROM $tableNameWHERE $sWhere" a między tablename a where powinna być 'spacja'
