I set up a featured image in a single blog, and I set my blog settings to: big image and raster.
Template : Wide.
Unfortunately always the dummy pic appeares first, and only after a click or tap(on the mobile phone), the featured image appeares. I need Jetpack to be active for my widgets on Shapely. So how can I solve this conflict / issue?
I checked the Inspector, it shows: img class="wp-post-image" src = "…/placeholder_wide.jpg"
I switched between Blog Templates “Wide“ and “No Sidebar“, I watched the result on all browsers and devices: there were no differences and placeholder_wide.jpg persists.
Is it an annoying cache problem or a bug somewhere in the settings?
Thank you for your help!
