I solved the problem finally. By adding the code snippets to the ENFOLD installation:

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;
}

add_filter(‘avf_blog_style’,’avia_change_tag_blog_layout’, 10, 2);
function avia_change_tag_blog_layout($layout, $context){
if($context == ‘tag’) $layout = ‘blog-grid’;
return $layout;
}

The code snippets in my child theme folder WERE IGNORED. WHY WAS THIS? It’s been a source of major frustration! And of course if I update the theme I will lose the custom mods.

Also is there a way to define the same image thumbnail sizing for images on the archive pages? They are being generated very large and resized in the browser (inefficient) > custom image size as within blog component is obviously being ignored. A fix?

UPDATE: If I DISABLE THE advanced layout editor option under blog layout and use the ie. ‘grid’ layout instead then the categories show correctly (with grid)! With a sidebar!

I have now just to change the default 3 column grid layout to 2 columns on the AUTO-GENERATED blog page – link below in private content. What php file do I edit?

I don’t like this solution as much as the other as I’m not able to control the image thumbnail size that is generated by the theme / WP so I’ve reverted to the custom layout for now and trying to find a solution.

Hi Ismael,
now i´m very sorry…i forgot to tell that i build the product with the advanced editor and i choose a gallery modul, Big picture with thumbnail. The gallery is nothing from woocommerce it´s from enfold. Is there a possibility to have the thumbails at the right sight? Plz… :-)
Best regards,
Alexander

What does this error mean? Did you log in to my website, to wp-admin?

This is the page: http://truenaturetrails.com/home/?preview_id=11&preview_nonce=53b291d1bf&_thumbnail_id=-1&preview=true. This link is a copy of what I see in my browser when I am logged in op wp-admin. All my pages are hidden because my website is not finish yet. So you have to log in first to see what I mean.
Thanks for your help!

I found on another post you can use the portfolio shortcode in a sidebar text widget which has worked quite well!
…but I would still like to know why the regenerate thumbnail isn’t working for future reference, many thanks

hmmm, i wonder if we’re miscommunicating with each other, because now I’M confused.

firstly, i don’t want to have to use a whole plugin just to change this one image size. i’ve seen reference to the plugin you mention around on this forum, and i looked in to it, but it hasn’t been updated in a while & wordpress gives a warning about that. besides, the screenshots of it look very confusing.

so, i’ll try to re-explain what we’re trying to accomplish…

on pages with sidebars, and only there, i have placed the Enfold Child Theme Latest News: Featured News widget.

by default, when rendered on page, this gives the feature image thumbnail at a very tiny size, floated left, with the title & date to its right.

we want instead for this to have a large image (as large as will fit within the padding of the sidebar), not floated, & the title & date below it.

i’ve changed the css to make it look like this, but as you know, the actual image size is not changing with that, thus it being blurry.

SO, how can i change this one particular image size?

note, the php code i ‘had’ in the functions.php (mentioned above) DID work for changing this image size correctly; but the bad side-affect was that it also changed the wp-admin thumbnails.

i do NOT want any of the wp-admin pages to change.
i do NOT want to change the feature image single latest blog post on the homepage either (i only mention this because it also uses the feature image of the latest blog post, but not from the widget, from the page editor).

does that make more sense?
thanks.
