Parallax effect work only when connected to admin panel (don’t work for users)

I put an absolute image with parallax effect on my homepage with the plugin “advanced addons” for gutenberg , everything was working fine either with last updates and i can see the effect work fine in my admin panel preview too, but recently the live version for users seems to not apply the parallax effect.

I already tried to desactivate plugins to test and find any conflicts without success, i just see that the parallax don’t work on admin panel too when elementor plug in is desactivate.

If anyone have hints or answer i’ll be glad to hear it !

ps: i try to do the effect with only free plugins , don’t have any pro or upgrated features ??
