IonPopup not showing up

[ksendra]

Hi,
I went back to a 3-4 month old project that was done with meteoric:ionic. I've updated all packages to the latests versions as well. But now when I start the app - ionPopups are not showing up on click. I can see that the HTML code is being added to the source, but nothing is visible.

I tried the example from Guide.md but received the same result.

What could be the problem with this?
Thanks

EDIT: There was a display: none attribute in the .backdrop class - this attribute is not turning off when you call the popup - that's why it's invisible. I changed "none" to "inherit" but it that a valid solution for this?
