Hi again,
together with @Rohitc, we are working on Air quality information for Sheffield (GB). There are still some quirks with the embedding of panels, probably related to Wordpress. At post #14, we can see everything works just fine in general.
Here, we might try to figure it out together.
With kind regards,
Andreas.
Hi Rohit,
Excellent. I can see that requests to grafana.panodata.net are being made in the JavaScript console. However, I am only able to see the “Tweets” box on this page, none of the iframe content is visible. I am using Firefox 85.0.2.
Cheers,
Andreas.
I just inspected the source code of the page at https://sheffieldair.gopingur.com/ and wanted to report back to you about it.
width="1000".</iframe> tag is missing.Maybe fixing those quirks will make the iframes render properly on Firefox already?
Indeed, I fixed them. The website works again as you can see, thanks so much for spotting the errors. However, the panels seem to be not connecting - similar prior to whitelist.
That made it work, thanks.
I made a mistake on the Nginx configuration. Fixed now!
Ah yes, solved, thank you so much 
sheffieldair.co.uk is live and working. Very early stage, but it works!
Great! Enjoy your work, spread the word and keep up the spirit.
