How do I remove dates from the scroller under the navigation, in the category drop down menu and the post info on the category page?

To remove the date in the DW Focus. Please follow the jetpack’s guideline in the Blog article on how to use Edit CSS here. http://designwall.com/blog/using-jetpack-custom-css-for-your-wordpress-site/
After that, just add the following code to the Edit Css.

#under-navigation .dw_focus_headlines .headlines .time_diff { display: none; }

.navbar .nav .menu-item-object-category .sub-mega-wrap .subcat span { display: none; }

– To remove the post info on the category page, you can open the content-archive.php file find the line 48 to line 52, then remove the following code:

<?php _e(' - ','dw-focus'); ?>
<?php echo dw_human_time(); ?>

– if you want to remove the date from the single post you can add the following code to the Editor CSS:

.entry-date { display: none; }

Hope this helps !

To resolve this issue please follow my instruction here:
1. Add following code to custom wp_head in Dashboard / Appearance / Customizer / Custom code

<style>
@media (min-width: 980px) {
 .archive .content-inner.layout-grid { 
 overflow: hidden;
 }
 .archive .content-inner.layout-grid .hentry { 
 height: auto; 
 border-bottom: 0; 
 margin: 0; 
 padding-top: 20px; 
 position: relative; 
 overflow: visible;
 }
 .archive .content-inner.layout-grid .hentry:before { 
 content: ''; 
 position: absolute; 
 top: 0; 
 width: 500%; 
 height: 1px; 
 background: #ddd;
 }
}
</style>

2. Open content-archive.php file in /wp-content/themes/dw-focus/content-archive.php
3. Replace following code – line 100

<?php the_excerpt(); ?>

with: 

<?php the_content('Read more...'); ?>

Hope this helps !
