Yes, it’s a WordPress.com option. It’s on per default, via the Jetpack plugin.
Anyway, we can close this now. Thanks for the help.
I disabled “lazy load images” in WordPress and this fixed the issue.
That’s a shame because I’d like to have that on, but it’s not a biggie. You may want to file a bug report on your end, though.
Thanks!
Something else I found: it doesn’t happen on the first page view. Only second and thereafter. So perhaps it’s some caching issue.
Thank you for the offer! Sorry, I am not allowed to do that. But perhaps if you tell me the things you were planning on investigating, I could do it?
– 1: Try disabling all plugins and enable one after the one
– 2: What else?
Updating to the latest theme (3.1.3.5) did not help.
Resolving plugin conflicts did not work.
