Can you show your html? On html your atributte for click is like'click()' ? Try to change for (click)="anyEvent()"

<ion-header>

<ion-navbar>

</ion-navbar>

</ion-header>

<ion-content padding>

<img src=“assets/imgs/Logo.jpg” alt=“Logo” class=“center”>

<ion-list>

<ion-item>

<ion-label floating>Email</ion-label>

<ion-input type=“text” [(ngModel)]=“email” name=“email”></ion-input>

</ion-item>

<ion-item>

<ion-label floating>Password</ion-label>

<ion-input type=“password” [(ngModel)]=“password” name=“password”></ion-input>

</ion-item>

</ion-list>

<div padding>

<button block ion-button (click)=“SignInAdmin()”>Admin</button>

</div>

</ion-content>

this is admin login.html

Try this way

<form> <!-- Form submit-->
  <ion-item>
    <ion-input name="authUsername" [(ngModel)]="authUsername" type="email"></ion-input>
  </ion-item>
  <ion-item>
    <ion-input name="authPassword" [(ngModel)]="authPassword" type="password"></ion-input>
  </ion-item>
  <button ion-button block round type="submit" class="padding-left-row" text-capitalize (click)="executeLogin()">
    Log-in
  </button> <!-- Type submit-->
</form>

same problem…

<ion-item>

<ion-input name=“authUsername” [(ngModel)]=“authUsername” type=“email”></ion-input>

</ion-item>

<ion-item>

<ion-input name=“authPassword” [(ngModel)]=“authPassword” type=“password”></ion-input>

</ion-item>

<button ion-button block round type=“submit” class=“padding-left-row” text-capitalize (click)=“executeLogin()”>

Log-in

</button>
