Do the problems occur in the default theme with no plugins?
I may misunderstand WPyogi, but the default theme is twenty twelve, correct? When I activated twenty twelve for a short time, I was still unable to set a featured image. Upload works fine, but setting a featured image does not.
If you meant a different theme, please tell me and I’ll try it immediately, thank you.
Also, images inserted into posts work fine, should have said.
Update: currently the site is set to twenty twelve but only chrome is showing the site with this theme; all others are showing the site in twenty eleven, which I deactivated some time ago. I should note that I am not signed into any of those browsers as the admin, which could have something to do with the different theme setting.
Yes, as of recently, twentytwelve is “the” default, though twentyeleven can also be used for troubleshooting. Looks like that’s what you have live, which is fine.
Looks like you currently have SuperCache enabled on that site, so that should be disabled and cleared.
Also, try resetting the plugins folder -they can sometimes refuse to deactivate completely from the dashboard:

Okay thanks. Had deactivated them all yes, but have renamed the plugin folder and all browsers are showing the site in twenty twelve. I’m afraid I don’t know this theme, it displays post thumbnails by default, yes? If so none of the post featured images are showing. Starting with the second post, all have featured images set but are not showing.
Similar problem on my site (http://stevensautomotivemuseum.com/) since upgrading to 3.5.1
On posts since the upgrade I cannot get the featured image to show regardless of if I selected one. Before it was automatic to get the lead image to show. running twenty ten.
No resolution on my thread http://ww.wp.xz.cn/support/topic/problem-with-thumbnails-on-home-page?replies=7
If you get a solution, can you let me know?
@stevec106 No luck yet but if you checked the notify me of follow-up posts via email checkbox below the reply box then you should get notices.
I am currently running another site elsewhere on 3.5.1 and building another site offline using the same version. Neither has problems with featured images. So I’m thinking one clear solution may be… reinstall WordPress. None too happy at the thought but it might clear up the issue.
UPDATE: Just attempted reinstall of WordPress files: kept wp-content, deleted all other files, uploaded WP and did overwriting of wp-content. The problem persists.
Enabled database repair and ran the script. Some database errors could not be repaired. The script instructed me to copy/paste the following to these forums for help:
wp_posts: 5 clients are using or haven’t closed the table properly
wp_comments: 4 clients are using or haven’t closed the table properly
wp_options: 6 clients are using or haven’t closed the table properly
wp_postmeta: Table is marked as crashed
wp_terms: 1 client is using or hasn’t closed the table properly
wp_term_taxonomy: 4 clients are using or haven’t closed the table properly
wp_term_relationships: 1 client is using or hasn’t closed the table properly
Anyone who can tell me how to fix these errors gets a cookie.
