I'm getting the error: "Whoops! Looks like you are not connected to the server. P2 could not connect with WordPress."
when trying to reply to comments/posts on P2, I'm on v1.5.2
Anything I can do to fix this?
This may be an issue with permalinks and Ajax. If so, the solution is simply to refresh your permalinks, by visiting Settings -> Permalinks
in your admin, and clicking "Save".
I just reset the Permalinks to default. And then reset them to the 'Post Name' configuration. It seemed to work.
