But we recommend to create a backup before just in case.

Hello,

You need to insert the following code into custom.css file:

.menu > ul > li > a {
    font-family: Georgia;
}

Change the font name to the required one.
Also don’t forget to enable custom.css in Theme Options > Custom CSS > On.

Please try to use this code to have the menu down:

.header-type-3 .main-nav .menu {
    margin-top: 120px;
}

Hello,

This can’t be changed by default in our theme. But you can edit custom.css and insert the following code:
.main-nav .menu > li .nav-sublist-dropdown { top: 70%; }

How to create custom.css file you can watch here.

Hello,

I’ve tried to add categories to the menu on default theme and the issue is present there too. It can be caused for the reason you’ve increased the menu items limit. That’s why new items can’t be saved. Here are some explanations:

Hello,

You can make color changes in Theme Options > Color Scheme and/or > Typography.
If it doesn’t match your requirements you may edit custom.css. Don’t forget to create it in the theme directory and enable it in Theme Options > Custom CSS > On.

Hello,

We’ve taken into account your requests. Some of them are already fixed:
3. You can use Place in header top bar widget area (language field in header);
4. It’s already fixed and spacing is added;
7. We’re working on it and the next theme version will have VC as a separate plugin;
8. You can turn on/off sidebar for each post when editing it. At the right side you’ll find the options “Page Layout”;
9. Visual Composer will help you to create columns.

Hello,

Sorry for a long delay.
There is a bug in accordion shortcode. We’ll fix it in the next update.
For now you can use the following shortcode to collapse the tabs:
