I have just been on your site and it certainly seems to be behaving erratically. Do you have any outdated templates? Or have you merged any templates since upgrading?
I combined template, as was recommended during installation.
I no modify template.
What can you recommend? Thanks
I see in XMG ( xengallery_media_block)
it
data-slide-width="{$slideWidth}"
data-responsive-wide="{$wide}"
But in ACP cant search for this value
