We built our new site at a staging URL. We then moved it to the live site and everything works fine -except- for the 'Posts' page.
On that page, the image specified as the thumbnail continues to point to the staging URL's img. Like this (see the src attribute):
<div id="primary" class="content-area">
<main id="main" class="site-main" role="main">
<header>
<div class="post-thumbnail">
<img src=".jpg" class="attachment-post-thumbnail size-post-thumbnail wp-post-image">
</div>
I tried going into PHPMyAdmin and searching wp_options and wp_postmeta thinking that the URL or image was stored somewhere in those, but I could not find it.
Can someone tell me where this option/value is stored for the theme?
