I’ve created this event to validate our plugin and it 's working fine with our plugin but when i am trying to save other plugin “PayPal” configuration, i am getting “Form PayPal could not be saved” error msg, so how i can prevent to call “validateForm” this function to other form submit event.
//Event which I’ve created in bootstrap file
$this->subscribeEvent(‘Shopware_Controllers_Backend_Config_Before_Save_Config_Element’, ‘validateForm’);
