# Issues

Something wrong may appear in the page markup. BabelShark will try to indicate the problems.

### Nested \_\_ class

One of the most often issues is a presence of nested elements with `__`class:

```html
<div class="__ parent">
    Some content
    <a href="..." class="__">is here</a>
</div>
```

You may see that inner `__` is located within outer `__` element. This will cause issues while localizing strings.

BabelShark indicates the problem in translations list:

To fix this issue, edit your HTML and avoid nested elements with `__` class.
