Hi @savanna2,
We do our support in English, so I’ll be replying in English for now. You’re welcome to continue in Japanese and I can enter your message into Google Translate, or you can continue in English if you’d prefer.
The translation of your message says that you are having trouble with the Slideshows. Are you referring to the Jetpack Carousel feature?
It doesn’t look like this feature is activated on your site, so please make sure that you activate it by following the instructions in this article: https://jetpack.com/support/carousel/
The translation also said that slideshows are working on the demo screen, but not on the display screen. Can you please clarify what you mean by this? Could you share exact URLs of where the feature is working and where it isn’t?
Thank you!
