Hi, I have a problem when I activate a plugins, get this error;

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [1203] User hiusis already has more than 'max_user_connections' active connections' in /home/jafinoc/test/config.php:104 Stack trace: #0 /home/jafinoc/test/config.php(104): PDO->construct('mysql:host=loca...', 'test', 'test2019', Array) #1 /home/jafinoc/test/Liten/Helper/Set.php(212): {closure}(Object(Liten\Helper\Set)) #2 /home/jafinoc/test/Liten/Helper/Set.php(76): Liten\Helper\Set->Liten\Helper{closure}(Object(Liten\Helper\Set)) #3 /home/jafinoc/test/Liten/Liten.php(126): Liten\Helper\Set->get('db') #4 /home/jafinoc/test/app/src/Hooks.php(224): Liten\Liten->get('db') #5 /home/jafinoc/test/app/functions/hook-function.php(83): app\src\Hooks->load_activated_plugins('/home/jafino...') #6 /home/jafinoc/test/app/functions/hook-function.php(554): load_activa in /home/jafinoc/test/config.php on line 104

happens when I activate any plugins, but if I turn it off, the system works great
