Elementor features not working

Hello,

I am having problems in https://allmydemos.net/mercadolibrepack/inicio/

Header links do not work, “Servicios” “Contacto” are very well configured but they send you to the home page and not to the #servicios, for example.

Whatsapp link iin the header is properly configured as https://api.whatsapp.com/send?phone=541159496764. HOwever it gets written twice https://api.whatsapp.com/send?phone=https://api.whatsapp.com/send?phone=541159412345 and sends to an error page.

In the middle of the page, the section VISITANOS does not display the image background. In some devices you´ll see grey color , in other devices, it is completely blank,

I have problems with changes made. At times, they don´t reflect.

Also, for example, trying to configure a background color for pc in a given section, and then I change this section color in mobiles, or tablet, these colors affect the pc color configuration. Same goes for fonts colors.

They get to be all the same. Meaning, I cannot give different colors or different font settings to the different devices.

I have cleared every cache, Elementor cache, admin cache, my pc cache Also, I tried disabling and reactivating my plugins but unfortunately all these problems persist.

Please help

Thank you very much

Liliana
