woocommerce doesn't show simple products price

hi, as I wrote in the title, woocommerce does not show the prices of simple products. It seems to be a problem with Enfold, because if I activate the default theme “Twenty Seventeen” I can see the prices normally.

Looking in the old threads I found some solutions, like that of deleting a line in config.php in the woocommerce folder of the theme, but it does not work.

I tried to disable and delete the woocommerce plugin and reinstall it, to update enfold, wordpress and all the themes and translations to the latest version, but it does not work.

I’m in big trouble, can you help me?

I have attached the login credentials

thanks a lot
