Editing main menu and banner section

Hello everyone, I'm trying to make some edits to a website but I'm struggling. I'm leaving info about the site:
link: https://webtc.eu
The website is using bootstrap
CMS Web Engine
Database Patch Level: 1.5.5
PHP Version 7.4.33

What I want to do is:

1. Add new tabs to main top menu.

• The menu "Bioplastic" should be there but is not displaying sub menus right. Bioplastic is a category with products in it. I want sub menus to be those items. Right now it is showing info from somewhere else.

2. Remove the animation of the slider/banner in header.

• I want the banners to have 3 images in slider with auto rotation and arrows.

I've been looking into c panel's file manager but without success. I found addon_domains/webtc.eu/www/root/includes/languages/english/bootstrap/header file but I do not see the same menu as it is in the website. I also Do not find where to edit banner animation and rotation.

If I forgot to leave any information that could help, please tell me.

I will be thankfull to any help :) Have a nice day!

Wow, nice looking site, but ...

1. The version of Zen Cart, Bootstrap and jQuery that is in use are each very old and, thus, should be updated.
2. It looks like (it's hard to tell with all the customizations) the Bioplastic category (if it has enabled products) *should *show on the top menu. I'll note that that's most likely controlled by the site's template's /common/tpl_header.php.
3. I've navigated a bit and have no clue as to where to actually find a product to purchase.

You're not necessarily going to find anything in the cPanel File Manager, although logging into the admin and poking around you might find a couple of configuration settings that can help.

Hello and thanks for your reply.

This website does not have any products to sell directly. There is a shop. subdomain which is an eshop of the website.

The main menu is working really odd. The Bioplastic tab should show the products from the category but it is showing wrong content and I can't understand why.

I'm leaving screenshots so you can uderstand me easier.

Well, for starters, the setup you have is "illegal" in Zen Cart - you're not supposed to have products AND categories on the same level. If you do, products take precedence and categories are ignored.

The "BIOplastics" menu is obviously coded to show Manufacturers and not products or categories.

Your site is not using any of the freely available templates and I'd dare say it's custom built with (quite) some custom code. Without seeing the code or knowing what was done and how it's supposed to work, I doubt you'll get much help here since it's 99.9% custom coded for your site...

Thanks for your time and replies! I will try to figure it out :)

One last thing .. Do you know where I can download french flag that looks the same as others because I downloaded this one online and it is different?
