In Cassiopeia template banner module the html code (div class="container-banner full-width") is being blocked by users that use kaspersky security programs with anti-banner feature enabled.
The kaspersky anti-banner has a blacklist that includes "container-banner" as a red flag. So it instructs the browser to apply display:none; to this class.
I tested on local server it is not blocked. Only on live sites. You can see the video that i made from https://cassiopeia.joomla.com/

I hope the joomla team corrects this because it affects a lot of people and is very frustrating.

The use of the module as i understand, is to show an image or it can be used for slide images, etc. So why name it container-banner and not container-slider or container-hero-image? Banner is something else, used usually to show advertissments.
It may be a false positive from kaspersky in this case, but the problem remains and i dont think that kaspersky will change it.
So why dont we change it? I dont think it is so difficult to rename the class. The most important thing is accessibility for the users in my opinion.
it is easy to change it but then you will break every exiting site template that uses that class
Maybe then change it only for joomla 6.* version?
If we change this and the next user start a module with '<div class="contaienr-banner"> .. </div>'?
I feel your pain but its really not something we can change in core. If you are effected then you just need to create an override in your own template
This should be closed as not planned

ok, thanks
I think that it is a error in kapersky, not in joomla. Everyone can choose class names in HTML and CSS, not only in joomla.
