The slider has a width of zero

Can you link to a page with the issue?

Hello Andrew, example

login : lalune
pwd: 1formanet

Are you using a plugin called “Jetpack” for this slideshow?

I use Jetpack but not for this function; I try to desactivate it to see and tell you in a few minutes

When I deasctivate jetpack I have no more slideshow; only a display in column

I would recommend you post on Jetpack’s support section about this: https://www.ads-software.com/support/plugin/jetpack#postform

Ok, I go ! Thanks
