I've been looking at my Activity Stream with that "Inspect Element" editor thing in Chrome, and the CSS classes for the link and image embeds aren't being included.
I've made some alterations to the output and that didn't effect the output. But I woke up this morning and the CSS classes were being printed on the page and it was styled the way I wrote the CSS. But after a while it reverted back to how it was.
All the link/image containers come out as are <p> tags.
What's conflicting with link_tag_template.php etc?
