So in your child theme folder, you’ve completely replaced screenshot.png and it’s not updating in the Dashboard? All browser caches clear? That should be all you need to do.
Thanks yes I have done that but no luck π
I have tried flushing the cache from the hosting end also. Still blank.
Tried making the size smaller and reuploading.
Tried opening on a different computer.
Always blank.
mmm well I hadn’t thought to check it that way π I have tried uploading an image that works on another site too but it’s also blank so maybe it’s an FTP/upload issue … thank you will try uploading a different way.
