As the title say, in settings->reading->is set summary & in customizer is set excerpt for 54 words, but after the 1.2.9 update, this does not function anymore.
Are you using post formats for any of your posts? For example, the image or gallery post formats will display the entire content (so images will appear).
Can you link me to the site where the excerpts are supposed to display?
The site: http://roxirose.com/
Even if we talk about the homepage, or every category shown in the menu, the posts were set to image post type and worked fine, until the update.
