Hi @jonaslismont
This looks like the slider loading animation that should go away as soon as the slider is loaded. Could you please contact me on support@nextendweb.com and send me a link to your site to see the problem? In your email, please refer to this topic!
Thank you Ramona, I just sent an Email.
After a direct intervention of the awesome Smart Slider support (thumbs up Roland), it appeared that this bug was related to a problem with the Smart Block plugin that was duplicating my page built with the SiteOrigin Page Builder in the footer. I removed the Smart Block plugin and everything is back to normal.
We are happy that we could help! 🙂
