Hi,
To make the removal of date and comments universal, change the css to look like this:

.slide-meta { display: none !important; }

About the css places:
1: The child theme style.css, in the WordPress > Appearance > Editor > Child Theme > Stylesheet is recommended for your css to keep your child theme complete and in one place. But with the merged css feature of the theme you may need to rebuild the merged files for your css to show after adding code there. To do this simply save your theme settings with the big blue button “Save all changes”
2: The Quick CSS is very easy to use and handy for sites that don’t use a child theme, and sites that do. Many use this because they only have a couple of code snippets. When you save the code here the merged files are updated automatically.
3: The WordPress > Customize > Additional CSS is a WordPress feature, but works very well, it’s the last stylesheet loaded by the site so it will easily overwrite any tough css changes, plus it offers good error checking which could help you ensure your code is right. The only downside is that code here will stay in effect if you change themes, until you remove it. But you’ll never do that, right? :)

For your custom menu I gave it a try, but it adds a background color to your category page, see if you like it.

Hi,
I fixed your css to remove the grid comment count and date.
To change your category pages to a grid style I added this function to your child theme functions.php:

add_filter('avf_blog_style','avia_change_category_blog_layout', 10, 2); 
function avia_change_category_blog_layout($layout, $context){
if($context == 'archive') $layout = 'blog-grid';
return $layout;
}

Now you can choose if you want a sidebar on the category pages at Enfold Theme Options > Sidebar Settings > Sidebar on Archive Pages
I then added your sub-menu to your category pages with this function in your functions.php:

add_action('ava_after_main_title', 'ava_after_main_title_mod_category');
function ava_after_main_title_mod_category() {
	if(is_archive()) {
		echo do_shortcode("[av_submenu which_menu='center' menu='' position='center' color='main_color' sticky='true' mobile='disabled' mobile_submenu=''][av_submenu_item title='Menu Item 1'][av_submenu_item title='Menu Item 2'] [av_submenu_item title='Menu Item 3']
[/av_submenu]");
	}
}

You will notice in your functions.php you have two sets of similar functions for the sub-menu, one for single posts and one for archives (categories) they are well marked, should you want to change which menu shows on each.

For your banner image at the top of your category pages, do you want this to be the same image for all categories, or a different image for each category?
One option is this plugin: Categories Images

Hi,
Here is a working example, note that the color of the menu items are white, (first rule) unless it has the class “current-menu-item” in which it will be black, (second rule)

.html_av-overlay-side #top #wrap_all .av-burger-overlay-scroll #av-burger-menu-ul a {
    color: #fff !important; 
}
.html_av-overlay-side #top #wrap_all .av-burger-overlay-scroll #av-burger-menu-ul .current-menu-item a {
    color: #000 !important; 
}

If you already have similar code in your css, use the above to help make the changes, if you don’t have anything similar yet, then go ahead and add the above css.

Hi,
Sorry, the statement doesn’t make sense, but it will be good to see your files and site when it’s on the troubleshooting server.
I see your logins above, and I was able to login to the site & ftp.
This is for the live site, correct? I see it is using PHP v5.3

Let us know when you have the troubleshooting server running and the login details for it in the Private Content area, so we can assist with a theme update on it.

Best regards,
Mike

Hi,
You mean the cache of your browser, right?
Try incognito or in-private mode.
Please see screenshots in Private Content area.

Hi,
Instead of using the active state, try using the “current-menu-item” class, and try putting the border around the “li” like this:

.avia-menu li:hover {border: 1px solid #ffffff!important;  border-radius:100px !important; }
.avia-menu li.current-menu-item {border: 1px solid #ffffff!important;  border-radius:100px !important; }

Is this the style you are looking for?
Here is a similar project that perhaps some of the code will be helpful:

Hi,

Hey Christel,
It sounds like you are going to the right place, but I will add some screenshots to be sure.
First click a slide you wish to edit:

then edit the title and caption:

Then save, and back on the main slider window scroll down to ensure the “Use first slides caption as permanent caption” is not checked:

Then save again and publish

Best regards,
Mike

Hi,
Try this code in the General Styling > Quick CSS field:

#top.single-post .title_container .container {
    display: flex;
    justify-content: center;
}
#top.single-post h1.main-title.entry-title a {
font-size: 70% !important;
}

Please adjust to suit.

Best regards,
Mike

Hi,
Oh, I see, on the site that is down did you update via ftp? If so, you will need to remove the old theme folder first (wp-content/themes/enfold/) then upload the new enfold folder.
Please don’t try to overwrite the theme folder, as this will leave old files behind, and cause a error.

For the site I logged into, I see the builder has this error:

Failed to load resource: the server responded with a status of 403 (Forbidden) /wp-admin/admin-ajax.php

Please check that the file permissions are correct and that .htaccess is not protecting the admin folder for security, or the webhost has mod_sec protecting the admin folder.
I also see that your PHP Version is: 5.3.28, you need a minimum of v5.6 this might be the issue with the other site if it is using the same PHP version.

Best regards,
Mike

Hi,
I assume that you have rolled back to recover, as I see your site is up & I was able to login.
Does you webhost offer staging sites to test the upgrade?

Mike
