@leocg well the rest of the site displays fine and it's worked in the past

@leocg Weird. It still won't display at my end

I cannot add things to basket on hobbycraft in opera.
It's not hobbycraft's end
It works on Chrome
Cache has been cleared recently
It must be another bug after the newest update.
I'm running Win7 64-bit
Opera v. 74.0.3911.203

Hi
So far I've only noticed this problem with one website:
https://www.zippi.co.uk
I just thought I'd report it as it's strange.
Basically the page displays as blank. No images, no text, nothing.

I've contacted the owner of the site and they are at a loss as it works from a mac their end using firefox, safari and chrome (Version 88.0.4324.192 (Official Build) (x86_64)). They have also checked to make sure no IP addresses are blocked at server level.

I have tried accessing the site via with Opera (74.0.3911.160), Chrome (Version 88.0.4324.190 (Official Build) (64-bit)), & Firefox (86.0 (64-bit)) (all the latest versions) on Windows 7 64-bit.
All other websites I've come across work.

Also it loads correctly on my phone and tablet apps - both chrome and Opera Touch App v.62 .
It's not just an issue with the latest version of Opera as I tried accessing the site months ago and presumed the company had gone bust but they haven't and many people can and have been placing orders.
I've tried disabling ad blockers and extensions.
I know that I've had this problem with one other website in the past (can't remember exactly which one and I got round it by using chrome).

When selecting inspect element from right clicking the page, it displays the page visibility as 'hidden' and '0' transparency and when I change these values to 'visible' and '100' the site's images and text appear. Obviously I can't save this and when I refresh it it all disappears like you'd expect.
Could this be something at the user's end?
I'd rather not uninstall and reinstall for the sake of one site, but for all I know it could be multiple sites, hence why I'm reporting it.

Thanks in advance
