Hello! Thanks for opening an issue with us! As this seems like more of a support question I will urge that you ask this question on our forum or on our [slack channel](https://ionicworldwide.herokuapp.com/]. Thanks for using Ionic!

Just to inform that I also have this error which is related to loader.dismissAll(). When you call it twice it throws this error.

It would be great if loader.dismissAll()checked if there are any loaders present and do nothing if none exist. I have loader.dismissAll() in multiple parts of my code (depending on certain conditions) and sometimes more than one runs and this error is thrown. I guess I could put my own if statements before each dismissAll()

I am having the same issue and I agree with @efares, it would be nice.

i fixed it with this it may help
```
constructor(
public loadingCtrl: LoadingController
) {

        this.loader = this.loadingCtrl.create({
            content: this.loadingText
        });

        this.loader.onDidDismiss(() => {
            this.loaderStatus = false;
            console.log('Dismissed loading');
        });

    });
}

loader: any;
loaderStatus: any;
public loadingText: any = 'Loading';

showLoading() {

    // this.loader = this.loadingCtrl.create({
    //     content: this.loadingText
    // });
    this.loader.present();
    this.loaderStatus=true;
    setTimeout(() => {
        this.loader.dismiss();
    }, 5000);
}

hideLoading() {
    if(this.loaderStatus){
        this.loader.dismiss();
    }
}

```
