fix scripts errors in my website, fix my header as it was before. -- 2

the page is [login to view URL] My header was perfect someone entered without knowledge and make many script errors so i want it just to be as before (Inicio Categorías Marcas Catálogos Ofertas ¿Quiénes somos? Contáctanos) all with the same font size, when you put the mouse on the top of any a box shows in the same size as all and separate estetically. When you make the website smaller the menu gets to three lines i want to be able to click it and make the menu appear, this have to be done on phone too (as the photo [login to view URL]). The image (44) is how the header was the only thing wrong is the social icons that have to be more to the right. Theres also a common problem that is fixed in the actual website but dont want it to be deleted. When you make the site smaller the website gets to a three line menu. i want this to be exactly as it looks right now. fixing the three line menu to be active on desktopand phone. Also theres two little mistakes that i want to be fixed appears to be simple. -The main photo its supposed to be a slideshow of three but its not working. -Where it says LOS MAS VENDIDOS its showing one product and its supposed to show four. -When you enter a product in the cart and enter enter in cart page theres a box that says ACTUALIZACIÓN i want it to be changed for ACTUALIZAR or to made the box bigger so it dosent see bad(image 47).
