Hi, Toufiq Unfortunately This is not working correctly. It is in the desktop view, but not in any of the other device views There are also two other elements which don't disappear in the Tablet and Mobile view.
Do you not think it is odd that the visibility issue work as they are supposed to in Preview mode but not in Live view? Is this more a caching issue that the old CSS code is not being replaced when saving the page, as the CSS must be correct at some point for the preview to work correctly?
I have upgraded to 4.0.5 and the issue persists as does the inability to add read more tag in the Article In 4.0.5 trying to save the read more tag in the article deleted the content of this article in SP Page builder I was able to recover that page but this is worrying. Is there a way to add the article-introtext and read more tag from within SP Page builder and not have to revert to the Joomla editor to add this content as this looks to be potentially very destructive?
