Content not showing on mobile

Hi, 

I have a problem with a clients website in mobile - it's showing sections / images but nothing else (meus, headings, text etc). 

How is it possible to fix? Website working fine on desktop. Also has working perfectly on mobile before - only recently stopped working.

Have attached a screenshot for reference.

Thanks

This is homepage or which page? And which section?

It's across the whole website - it's only showing the background

@tuanphan do you have a solution?

You try disable Animation on Site Styles. I see some opacity: 0 code on your site

or use this to Website > Website Tools > Custom CSS

.tweak-global-animations-animation-type-fade header, .tweak-global-animations-animation-type-slide header, .tweak-global-animations-animation-type-scale header, .tweak-global-animations-animation-type-clip header, .tweak-global-animations-animation-type-flex header, .tweak-global-animations-animation-type-fade footer, .tweak-global-animations-animation-type-slide footer, .tweak-global-animations-animation-type-scale footer, .tweak-global-animations-animation-type-clip footer, .tweak-global-animations-animation-type-flex footer, .tweak-global-animations-animation-type-fade section>.content-wrapper, .tweak-global-animations-animation-type-slide section>.content-wrapper, .tweak-global-animations-animation-type-scale section>.content-wrapper, .tweak-global-animations-animation-type-clip section>.content-wrapper, .tweak-global-animations-animation-type-flex section>.content-wrapper {
    opacity: 1 !important;
}

@tuanphan thanks - it's almost fixed. 

The problem is now I can't select the burger menu on mobile, and the menu colour doesn't change on scroll (goes from transparent to purple - #251940 )
