    Hello @morfjord,

    I hope you're well today and thank you for your question!

    I took as look at your site and it seems that in place of those commas there should be post categories/tags shown. Those however seem to be hidden so I assume that's on purpose. Therefore, comas are "left overs" that could be hidden with this CSS:

    .blog .post_categories {display:none;}

    To apply it to your site please open the page in your browser (being logged in as an admin) and then
    - enter "Upfront" editor by clicking on "Upfront" link in admin toolbar
    - click on "Theme Settings" link in Upfront's panel on the left
    - click on "add custom css rules" link in Upfront's panel
    - inside an editor that pops up at the bottom of the screen: scroll an existing content all the way down and add the code at the very bottom
    - save editor
    - save Upfront

    I hope that helps!

    Best regards,
    Adam
