Thank you for your reply Simion.
The problem appeared after recent WP update to 4.9.7
Yes, Facebook scraper reports 404 errors for my featured images.
And, yes, Yoast generates the same error. Yoast doesn’t work for me.
The only plugin that worked on other sites I manage is the WPSSO Core, but in the case of https://publicspace.gr with the Newspaper theme, it reports: Conflict detected — your theme or another plugin is adding meta property=”og:image” to the head section of this webpage.

Thanks again
I’m still searching!

Still no image. Neither on Facebook nor on Twitter.
SSO reports: Conflict detected — your theme or another plugin is adding meta property=”og:image” to the head section of this webpage.
Site is https://publicspace.gr
Is there any workarround or am I to keep posting the OLD WAY, i.e. posting the Image and adding the link to the Description

Thanls Simion.
I installed a clean wordpress 4.9.5, one theme (newpaper 8.7.4) and two plugins (Composer & Social Counter).
Again, I see no items in ADS tab!
The XAMPP PHP version is 5.6.33.
Could this be an issue?

EDIT: The problem is only in Chrome!
Firefox and Opera display the Ads tab OK.

You could
a. Rename these files e.g. as “newspaper_theme_example_placeholder_*.jpg” Some of us design sites for customers who are mad with security. I didn’t know that these files were added via your plugin and didn’t know how to explain it. My customers assumed that I was using my admin account to login and post on their behalf.

b. Remove the content and use an “X” on a neutral grey background so that the placeholder will LOOK like a placeholder that everybody is familiar with.

No need. I upgraded to Newspaper 8.5 and there is no problem any more.
Thanks for your great support.
Problem solved.

I am using the latest newspaper theme 8.2 with no plugins installed at all, yet the caption takes 100% of the area and creates a VERY bad impression of the site.
Is there a workarround?

Thanks for your reply, but it didn’t work for me.
On the other hand, I grouped every single item with font-family in style.css and now i’m changing only three items.
Check this out. It actually works:

Hi.
Well, I was looking for something like this:

html
{ font-family: serif; }

.td-logo-text-container .td-logo-text, .td-logo-text-container .td-tagline-text
{ font-family: sans-serif; }

body, p, .wp-caption-text,  .wp-caption-dd, .td-page-content .dropcap,
.td-post-content .dropcap,  .wpb_text_column .dropcap, .td_block_text_with_title .dropcap,  .bbpress .dropcap,  .woocommerce #tab-description .dropcap, .mce-content-body .dropcap,  .comment-content .dropcap, .td_block_author .td_author_wrap, .td_top_authors .td-authors-url a, .td_wrapper_video_playlist .td_video_title_playing, .tdc-missing-external-shortcode, .td-block-missing-settings,  .tdc_external_shortcode, .td-sml-caption 
{ font-family: Georgia, Times, serif!important; text-align: justify }

etc.
It’s the theme’s default typography, grouped by font-family
But ok. I did it my self.

🙂

OK. Thanks.
