Bug: resource not found on Android 4.0.4 (API 15)

[AKPWebDesign]

When attempting to load vector resources, we are getting this error:

android.content.res.Resources$NotFoundException: File res/drawable/ic_discord_logo.xml from drawable resource ID #0x7f080079. If the resource you are trying to use is a vector resource, you may be referencing it in an unsupported way. See AppCompatDelegate.setCompatVectorFromResourcesEnabled() for more info.
