featured image not well displayed

Can you replicate the problem using the default Twenty Twelve theme with all plugins deactivated?

I saw one post on the web. I deactivated all the plugins and activated very basic plugins. The same result. That’s why I tried to Wootheme. Exactly the same as Twenty Twelve. I also regenerated all thumbnails many times.

Can we see the site using the default Twenty Twelve theme with all plugins deactivated?

I deactivated all the plugins, everything. It didn’t help.

Can we see the site using the default Twenty Twelve theme with all plugins deactivated?

i will deactivate all plugins completely again in the next 5 seconds.

all plugins have been deactivated now.

And the theme? There is no magic bullet in these situations. This is just the start of basic troubleshooting and is a process of elimination deliberately designed to locate the root cause as quickly as possible by first removing the most obvious and common culprits via a series of (often) temporary steps. Do you want to locate and, hopefully, fix the problem on your site? If “yes”, then please help us to help you and carry out the changes that we suggest. Otherwise this is just a waste of everyone’s time.

sorry. the theme has been changed back to twenty twelve now.

i really would like to see thumbnails on the page. they are all featured images.

Can you please stop disabling right click on your site.

Yes, i have also deactivated that. Now there is only one plugin Woocommerce that is still activated.

can you please let me know whether you found any solutions? Thank you again for your help.

On that page, looks like WC code is affecting the image size:

.woocommerce ul.products li.product a img, .woocommerce-page ul.products li.product a img {
    box-shadow: 0 1px 2px 0 rgba(0, 0, 0, 0.3);
    display: block;
    height: auto;
    margin: 0 0 8px;
    transition: all 0.2s ease-in-out 0s;
    width: 100%;
}

can you please help with the problem? thanks
