Remove comment and date from post excerpt thumbnail

Delete the post-meta div from the thumbnail. Need help just let me know.

Please ask the vendor for help: http://wpshower.com/themes/sight/

These forums only support themes from here:

http://wordpress.org/extend/themes/

you can use a quick-fix to hide it with css, added to the end of style.css:

.grid .post .post-meta { display: none; }

however, it would be better to locate it in the theme files and remove it there.
just persist with the theme’s developers to get support.
