Hello,

Can you please help how to hide css content from popups window in like notifications, messages, likes etc.
Please see the content below:

Thank you
Kind regards

That would be your 3rd party extension causing that or some sort of custom echo somewhere. It's injecting HTML output directly into Joomla's buffer output likely via an echo for some reason. That's the wrong way for an extension to add CSS to Joomla. Find what's responsible for outputting that CSS and disable it.
