on performance reasons : you should familiarize yourself with image optimization.
f.e.: this image here: image1 is 524kb big
this image2 450kb etc. pp.

Since you are using the srcset option of enfold, you should ask yourself if increasing the compression level is not also an option for your images. Enfold offers a snippet for this; however, you would have to recalculate the thumbnails afterwards. Because the snippet only controls the compression during media upload.
for 55% compression instead of 0% ( Enfold let the quality level on 100 on uploading )

add_filter("avf_jpeg_quality", "avf_set_quality_mod", 9999, 1);
add_filter("avf_wp_editor_set_quality", "avf_set_quality_mod", 9999, 1);
function avf_set_quality_mod($quality) { $quality = 55; return $quality;}

This project was a conversion from an existing DIVI website.

Feel Positive Coaching ran by Fay Petcher is a holistic divorce and relationship coaching service. Fay is also an established Podcaster, Author and EFT Practitioner helping couples and individuals cope with narcissistic abuse, relationship trauma and infidelity.

The site was rebuilt in Enfold for ongoing support and performance features.
As part of the process the site was turned into a multi-page website from a one page design. Large padding and margins help give the site a modern – easy to scroll feel.
The logo and colour scheme were revised and entered into the Enfold theme control panel.

The site scores 95/100 on mobiles in web vitals helping the site load quickly on all devices.

Maverick Security Ltd
Maverick Security is a new startup Manned guarding (security guard) provider based in Derbyshire UK. They specialise in providing reliable security guards for business premises and events throughout the UK.
We were tasked with creating a simple recognisable logo that can be embroided and printed on clothing easily. The colour scheme was then transfered into Enfold for consistency.

The site has some bespoke performance settings including font preload and serving a different background image depending on the screen size. The site currently scores between 95/100 and 97/100 depending on the test run.

We had some issues getting Google to crawl the whole site (unrelated to rest of post). I have added links below to try and encourage Google to Index the entire site. I hope support do not mind! :) I will remove if it is successful.

First, have you checked the box to load thumbnails locally?
under Content Blocker – Youtube – this is besides your question a thing to mention.

_______
what kind of link is it – does it lead to a lightbox with the video? can you show me the site it concerns?

@Ismael,
Your wizardry worked again! I used this:
$size = strpos( $blog_style, 'big' ) ? ( ( strpos( $current_post['post_layout'], 'sidebar' ) !== false ) ? 'full' : 'full' ) : 'square';
I did not have to regenerate thumbnails… when the posts loaded they were initially disproportionate, but then they snapped to the proper proportions… and it looks like it stayed that way.
Note: Under blog layout > single post style, I have it set to single post with big preview image.
Thank you all!
Tim

Hi there, I’ve got this error also.
I’m running the latest theme, WP and using php 7.4.
What I see is the page heading, then something like:

[av_three_fifth first av_uid='av-us9ewl']

[av_gallery ids='4643,4642,4640,4641,4639,4638' style='thumbnails' preview_size='portfolio' crop_big_preview_thumbnail='avia-gallery-big-crop-thumb' thumb_size='portfolio' columns='5' imagelink='lightbox' lazyload='avia_lazyload' av_uid='av-35oe3s' admin_preview_bg='']

Happy to supply a link.

but allways think of : after changing these sizes – a regeneration of the calculated thumbnails had to be done ( see this again: Then regenerate thumbnails … )
You can read here about the influence of some parameters to those changed or new sizes: https://developer.wordpress.org/reference/functions/add_image_size/ – especially the crop ( true, false ) ;) seems to be important.

Dear All,
The more I look for solutions, the more I find it hard to believe that there isn’t a simple option in the ‘blog layout’ section to ‘show featured image as a responsive full size’. ?
Also, here https://kriesi.at/support/topic/full-size-featured-image-in-single-blog-page/ it says:
“You can actually modify the includes > loop-single.php file in your child theme to override the default thumbnail settings. Just look for this code around line 66:

 */
    $size = strpos($blog_style, 'big') ? (strpos($current_post['post_layout'], 'sidebar') !== false) ? 'entry_with_sidebar' : 'entry_without_sidebar' : 'square';

Set the default thumbnail sizes from “entry_with_sidebar” and “entry_without_sidebar” to “full” or “extra_large”.”

BUT, in my includes directory, there isn’t any file named loop-single.php. ?
