Question: [![enter image description here](https://i.stack.imgur.com/W3Zgd.png)](https://i.stack.imgur.com/W3Zgd.png)

So only within my sidebar widgets does this bullet above the widgets occur. I am not sure what custom css code to use to get rid of this. That is why I uploaded the picture of the inspect element to see if anyone can help me identify where the problem is coming from. Thank you so much in advance.

Answer: 
You want to use [Enumerable#`any?`](https://ruby-doc.org/core-2.4.1/Enumerable.html#method-i-any-3F):

```
arr.any? { |substring| str.include?(substring) }

```

The solution is very efficient, because this method ensures *short-circuit evaluation*, meaning, that if you have array of 100000000 substrings and you want to check whether your string contains any of these substrings, this method will stop right when its block returns `true`, meaning, that if the matching substring is first in the array, it will never check other 99999999 elements.
The reason you are getting that error message is because the `*` operator is telling Ruby to pass all the items of `arr` to `str.include?`. For those `arr` items, that is equivalent to writing `str.include?("aa", "bb", "cc")`.

As said in other answers, checking a condition is verified for any of the elements contained in an array, like in your case (where you don't want to check if all the elements of an array are substrings of a given string), is done using `arr.any? { |item| str.include?(item) }`.
