Thumbnails not displaying on web page
I have been struggling with correcting this error for a while now, I have no idea as to what is causing it.
The posts thumbnails are not displaying on the page, however the pictures in the posts are still there once you click in.
I tried using Regenerate thumbnail plugin, but that was too slow, and what bothers me more is that new posts are also not displayed without thumbnails.
I tried using wp-cli, but it freezes up after the 74th image and yester my site was down for about 2 and half hours.
Tried it again today and the same happened, not sure how the media regenerate activity overloads the web host.
My website address is https://iobservers.com
Any help will be greatly appreciated
