After updating the last patch on my best working install of the socialengine software I am getting this error when I try to like a photo or video recently posted in the activity feed. "An error has occurred processing the request. The target may no longer exist."
Per the other thread, have you set your privacy settings for that account?
I am not sure what you mean but after upgrading my troubled site I get the same error so it was something in that patch that did that to my site.
"An error has occurred processing the request. The target may no longer exist."
I tested on your site and had no issue liking a video in the feed.
I think it was fixed by updating the theme.
Oh ok that's good to hear.
