Home page don't load when the slider image is active

[SaraCastro]

Hi, 

I have bought a theme https://themeforest.net/item/cucina-kitchen-mega-store-responsive-prestashop-themes/23713177 
And unfortulatly i bought support too but it's impossible to contact the developer. As the website is getting ready, i have face a problem that is related to the image slider module that came with the theme.

When the module is active the home page don't load at the first time, only when i refresh it, that happens in every browser except on mozila firefox. The prestashop version is 1.7.6.7.7, heres a link to my website https://acenor.pcsolution.pt/

Can anyone give a help?

Tks
