Editing a post using front-end

Hey there,

I seem to be having problems with editing and upgrading listings. The following are my issues:

1) When hitting ‘edit post’ in a posting it brings the user to the ‘add listing’ page with the url ?pid=[# here]
The problem is that the data for that post isn’t populated and when submitted, it just creates a new listing instead of updating the current one.

2) I have CSS styling to customize my ‘add listing’ page, but when I hit ‘edit post’or ‘upgrade listing’ it brings me to the ‘add listing’ page but the styling isn’t there.

3) Same problem for the ‘upgrade listing’ button. URL has pid and package_id, but it simply creates a new post and data doesn’t populate from the relevant post.

Please let me know if I’m missing a specific setting or if you can help me troubleshoot this issues. Best,

Kevin
